Scott Jerome Parks died in 2007 from a radiation overdose. His slow, agonizing death captured headlines. Headlines were followed by a congressional hearing, where his dad shared of Scott's suffering and the need for reform in medical device and radiation safety.  As I learned of his story, it brought me to many more stories. The first being the Therac 25. Natalia Silvis-Cividjian also found the story of the Therac 25. She too became captured and harnessed its lessons to teach students the importance of effective software testing. Natalia is a lecturer at the Vrije University in Amsterdam and joins me to talk about software, radiation, and the tragedy of the Therac 25.To learn about Natalia's project to teach and preserve software bugs for teaching click here.

Fredrik snackar om Datatjej - en ideell organisation för kvinnor och ickebinära inom IT - och medicinsk IT med Gabriella Norman - aktiv i Datatjej bland annat genom att driva Datatjejs podcast. En av många insikter Datatjej försöker leverera är att det finns mycket fler jobb inom IT än man kanske anar utifrån, speciellt inte när man som ung funderar över vilken bransch man ska studera för och ge sig in i. Och man måste inte vara superhjältekodare för att trivas och göra väldigt bra och viktigt jobb i branschen. Vi diskuterar också att vara generalist eller specialist, och hur man ofta känner att den motsatta sidan mot där man själv ser sig är den som verkligen tillför de viktiga sakerna. Gabriella berättar också om Datatjejs årliga konferens, och givetvis hur du kan engagera dig i föreningen. Sedan pratar vi om medicinsk IT. Vad innebär det, och vad är likt och olikt mot annan utveckling? Hur hanterar och bedömer man risker, till exempel, och ser man annorlunda på testning än inom andra områden? Och hur bedömer och hanterar man risker när man använder AI för att analysera medicinsk data? Hur påverkar processerna kring medicinsk IT det vardagliga utvecklandet?

David, Rachel, and Sarah discuss the horrible things the Therac-25 did to six unsuspecting cancer patients, and how the company responsible for the machine responded (or didn't). Apologies for the poor audio for a minute around the middle of the episode.

David, Rachel, and Sarah start the story of medicine and machine gone very, very wrong. Warning for copious cat interruptions.

Der Therac-25 war ein medizinisches Bestrahlungsgerät. Durch einen Softwarefehler kam es zu sechs Zwischenfällen mit teilweise tödlichen Ausgängen. Fatal war, dass der Hersteller damals davon ausging, dass die Software keine Fehler haben könne. Denn im Vergleich zur Hardware unterliegt sie ja keinem Verschleiß. Das war eine Fehleinschätzung mit Folgen. Erst durch den Einsatz eines Physikers aus einer der betroffenen Kliniken konnte der verantwortliche Fehler gefunden und schließlich behoben werden. Die Geschichte des Therac-25 ist ein Paradebeispiel für Softwarefehler und den Umgang damit. Und übrigens: Software unterliegt einer Art digitalem Verschleiß. Man spricht hierbei von der sogenannten Softwarealterung. Sprecher & Produktion: Wolfgang Schoch Musik: BACKPLATE von https://josephmcdade.com

The successor to the Therac-6 and Therac-20 RadioTherapy machines would integrate the powerful DEC PDP-11 mini-computer to control all of the Therac-25s functions, including the safety interlocks, for the first time. In two years the 11 machines in service would overdose six people across two countries, killing three of them before they figured out why.With John Chidgey.This show is Podcasting 2.0 Enhanced Reports into the Incidents: An Investigation of the Therac-25 Accidents ‎Medical Devices: The Therac-25 The Therac-25: 30 Years Later A Usage-Model Based Approach to Test Therac-25 Good Computing: A Virtue Approach To Computer Ethics: Chapter 6 Links of Potential Interest: Therac-25 The PDP-11 Assembly Language PDP-11 Digital Equipment Corporation Programmed Data Processor Rad (unit) Order of Magnitude Myelitis Collimator Fatal Dose: Radiation Deaths linked to AECL Computer Errors Reactor Accidents: The Human Fallout An Overview on Radiotherapy: From Its History to Its Current Applications in Dermatology In MedTech History: Mammography The programmer behind the THERAC-25 Fiasco was never found AMA: My professor investigated the Therac-25 incident How history, principles and standards led to the safety PLC Support Causality on PatreonEpisode sponsors:Premium Jane: Premium Jane are a US-based provider of organic CBD products that meet the highest standards of quality and purity.

All’aumentare della complessità che sta portando l’attuale processo di digitalizzazione, non possono che aumentare anche gli errori che l’informatica porta con sé. In questo episodio parleremo di alcuni esempi molto esplicativi di quali sono i problemi reali dell’informatica che potrebbero avere conseguenze disastrose sul mondo che ci circonda. Partiremo dalla macchina per la radioterapia Therac-25, passeremo dal Boeing 737 Max, fino ad arrivare al Millennium bug. Nella consueta sezione delle notizie parleremo del nuovo servizio Amazon Fresh, di un brevetto presentato da Microsoft per la realizzazione di un chatbot virtuale in grado di replicare il comportamento di una persona e infine dei progetti di Stellantis per la mobilità elettrica. --Indice-- • Amazon Fresh sbarca in Italia (00:57) - DDay.it - Davide Fasoli • Vivere in eterno grazie a Microsoft (02:02) - DDay.it - Luca Martinelli • Stellantis si concentrerà sull’elettrico (03:08) - DMove.it - Luca Martinelli • L’informatica è imprevedibile (04:34) - Luca Martinelli --Contatti-- • www.dentrolatecnologia.it • Instagram (@dentrolatecnologia) • Telegram (@dentrolatecnologia) • YouTube • redazione@dentrolatecnologia.it --Brani-- • Ecstasy by Rabbit Theft • Be Myself by Tom Wilson

This is the week when the movement to reform Section 230 of the Communications Decency Act got serious. The Justice Department released a substantive report suggesting multiple reforms. I was positive about many of them (my views here). Meanwhile, Sen. Josh Hawley (R-MO) has proposed a somewhat similar set of changes in his bill, introduced this week. Nate Jones and I dig into the provisions, and both of us expect interest from Democrats as well as Republicans.  The National Security Agency has launched a pilot program to provide secure domain name system (DNS) resolver services for US defense contractors. If that's such a good idea, I ask, why doesn't everybody do it, and Nick Weaver tells us they can. Phil Reitinger's Global Cyberalliance offers Quad9 for this purpose.  Gus Hurwitz brings us up to date on a host of European cyberlaw developments, from terror takedowns (Reuters, Tech Crunch) to competition law to the rise of a disturbingly unaccountable and self-confident judiciary. Microsoft's Brad Smith, meanwhile, wins the prize for best marriage of business self-interest and Zeitgeist in the twenty-first century. Hackers used LinkedIn's private messaging feature to send documents containing malicious code which defense contractor employees were tricked into opening. Nick points out just what a boon LinkedIn is for cyberespionage (including his own), and I caution listeners not to display their tattoos on LinkedIn. Speaking of fools who kind of have it coming, Nick tells the story of the now former eBay executives who have been charged with sustained and imaginatively-over-the-top harassment of the owners of a newsletter that had not been deferential to eBay. (Wired, DOJ) It's hard to like the defendants in that case, I argue, but the law they've been charged under is remarkably sweeping. Apparently it's a felony to intentionally use the internet to cause substantial emotional distress. Who knew? Most of us who use Twitter thought that was its main purpose. I also discover that special protections under the law are extended not only to prevent internet threats and harassment of service animals but also horses of any kind. Other livestock are apparently left unprotected. PETA, call your office. Child abusers cheered when Zoom buckled to criticism of its limits on end-to-end encryption, but Nick insists that the new policy offers safeguards for policing misuse of the platform. (Ars Technica, Zoom) I take a minute to roast Republicans in Congress who have announced that no FISA reauthorization will be adopted until John Durham's investigation of FISA abuses is done, which makes sense until you realize that the FISA provisions up for reauthorization have nothing to do with the abuses Durham is investigating. So we're giving international terrorists a break from scrutiny simply because the President can't keep the difference straight. Nate notes that a story previewed in April has now been confirmed: Team Telecom is recommending the blocking of a Hong Kong-US undersea cable over national security concerns. Gus reminds us that a bitter trade fight between the US and Europe over taxes on Silicon Valley services is coming. (Politico, Ars Technica) Nick and I mourn the complete meltdown of mobile phone contact tracing. I argue that from here on out, some portion of coronavirus deaths should be classified as mechanogenic (caused by engineering malpractice). Nick proposes instead a naming convention built around the Therac-25.  And we close with a quick look at the latest data dump from Distributed Denial of Secrets. Nick thinks it's strikingly contemporaneous but also surprisingly unscandalizing.

HAPPY NATIONAL TYPO DAY! Jon us as we celebrate those typgrpacial erros that we all kno and love! Today we're celebrating with pal and comedian Pete Musto (midnightgardenersleague.com / Facebook: MidnightGardenersLeague)!! LET'S PARTY!! Find Holiday Party online – Patreon: patreon,com/HOLIDAYPARTY Twitter: @HOLIDAYPARTYPOD / Instagram: HOLIDAYPARTYPODCAST / Facebook: @HOLIDAYPARTYPODCAST / HOLIDAYPARTYPODCAST.COM Find Alyssa – Twitter: @alyssapants / Instagram: lettertalkpodcast / alyssapants.com Find Disa – Twitter: @cinnamonenemy / Spotify: open.spotify.com/user/1243777842 SHOW NOTES History/Fun facts about the holiday A typo, or typographical error, or misprint, is a mistake made in the typing of printed or electronic material. According to Wikipedia, the term includes errors due to mechanical failure or slips of the hand or finger, but excludes errors of ignorance, such as spelling errors, or the flip-flopping of words such as “than” and “then”. Most typos include simple duplication, omission, transposition, or substitution of a small number of characters. “Fat-finger syndrome” is a slang term that refers to an unwanted secondary action when typing. When someone’s finger is bigger than the touch zone, there can be inaccuracy in the fine motor movements and accidents occur. This action happens often with touchscreens, particularly when a person hits two adjacent keys on the keyboard in a single keystroke. For example, “buckled” instead of “bucked” There may also be “intentional” typos, which are typos that may be used deliberately for humorous purposes. For instance, the British newspaper The Guardian is sometimes referred to as the Grauniad given its reputation for frequent typesetting errors in the era before computer typesetting. Intentional typos are in notorious use on the internet. Some, such as “teh”, “pwned”, and “zomg”, have become in-jokes among groups and subcultures Then there’s typosquatting, which is a form of cybersquatting which relies on typographical errors made by internet users. A cybersquatter will typically register a likely typo of a frequently-accessed website address in the hope of receiving traffic when internet users mistype that address into a web browser. Deliberately introducing typos into a web page, or into its metadata, can also draw unwitting visitors when they enter these typos into search engines Cybersquatting refers to the act of registering, trafficking in, or using an internet domain name with bad faith intent to profit from the goodwill of a trademark belonging to someone else. The squatter then offers to sell the domain to the person or company who owns a trademark contained within the name at an inflated price. Once in the typosquatter’s site, a user may be tricked into thinking that they are in fact in the real site. Spam emails also sometimes make use of typosquatting URLS to trick users into visiting malicious sites  There are several reasons why a typosquatter may buy a typo domain: In order to try to sell the typo domain back to the brand owner To monetize the domain through advertising revenues from direct navigation misspellings of the intended domain To redirect the typo-traffic to a competitor To redirect the typo-traffic back to the brand itself, but through an affiliate link, thus earning commissions from the brand owner's affiliate program. As a phishing scheme to mimic the brand's site, while intercepting passwords which the visitor enters unsuspectingly To install drive-by malware or revenue generating adware onto the visitors' devices To harvest misaddressed email messages mistakenly sent to the typo domain To block malevolent use of the typo domain by others To express an opinion that is different from the intended website's opinion Since the emergence of online auctions, misspelled auction searches have quickly become lucrative for people searching for deals. The concept is based on the incidence that, should someone post an auction and misspell its description or title, regular searches for the item won’t find that auction. A search that includes misspelled alterations of the item would find most misspelled auctions. In fact, a series of third-party websites have sprung up allowing people to find these items. There have been different ways of marking typos over the course of typography technology When using a typewriter without correction tape, typos were commonly overstruck with another character such as a slash. This saved the typist the trouble of retyping the entire page to eliminate the error, but as evidence of the typo remained, it was not aesthetically pleasing. In computer forums, sometimes ^H (a visual representation of the ASCII backspace character) was used to "eras" intentional typos: Be nice to this fool^H^H^H^Hgentleman, he's visiting from corporate HQ. In instant messaging, users often send messages in haste and only afterwards notice the typo. It is common practice to correct the typo by sending a subsequent message in which an asterisk precedes the correct word. In formal prose, it is sometimes necessary to quote text containing typos or other doubtful words. In such cases, the author will write "[sic]" to indicate that an error was in the original quoted source rather than in the transcription. Sic is derived from the Latin “sic erat scriptum” or “thus it was written” An “atomic typo” is a typo that happens to result in a correctly spelled word that is different from the intended one, and since it’s spelled correctly, the spellchecker cannot find the mistake. Examples include “unclear” instead of “nuclear”, “you” instead of “your”, “Sudan” instead of “sedan”, “Untied States” instead of “United States”, and “the” instead of “they”. The term was used at least as early as 1995 by Robert Terry. The Sedan/Sudan example actually happened in real life in 2005, leading to a diplomatic issue with Sudan.  Storax Sedan was an underground nuclear test conducted in Area 10 of Yucca Flat at the Nevada National Security Site on July 6, 1962 as part of Operation Plowshare, a program to investigate the use of nuclear weapons for mining, cratering, and other civilian purposes. The radioactive fallout from the test contaminated more US residents than any other nuclear test. The Sedan Crater is the largest human-made crater in the US, and is listed on the National Register of Historic Places. Ellen Tauscher, a Democratic member of the US House of Representatives from California, used Sedan as an example of a test which produced a considerable amount of radioactive fallout while giving Congressional testimony on the containment of debris from nuclear testing. However, the name “Sedan” was incorrectly transcribed as “Sudan” in the Congressional Record The international community quickly took notice, and Sudanese officials responded by stating that “the Sudanese government takes this issue seriously and with extreme importance”. The Chinese Xinhua General News Service even published an article claiming that the Sudanese government blamed the US for raising cancer rates among the Sudanese people. Despite the US embassy in Khartoum issuing a statement clarifying that it was a typographic error, Mustafa Osman Ismail, the Sudanese Foreign Minister, stated that his government would continue investigating the claims Gives a whole new dimension to the term “atomic typo” Fun facts and anecdotes! From a 2009 mentalfloss.com article and a 2017 article on listverse.com In 1631, a widely distributed Bible came to be known as the “Sinner’s Bible” when readers noticed that a very important “not” had been omitted” from Exodus 20:14, making the 7th commandment read “Thou shalt commit adultery.” This resulted in printer fines and recalled copies, with only 11 copies known to still exist today On July 31, Austin M. Patterson, chemistry editor at Merriam-Webster, sent an internal communication to the printers that included the phrase “D or d, cont./density.” The intention was to add “density” to the existing list of words that the letter “D” can abbreviate. The printer misunderstood, and instead printed a single, run-together word: dord, meaning density. The typo got past proofreaders and appeared on page 771 of the dictionary in 1934. It wasn’t until February 28, 1939, that an editor noticed “dord” lacked an etymology, and an urgent plate change soon followed The Therac-25 was a device from the 1980s that was designed to treat cancer patients with controlled bursts of radiation. Radiation is obviously extremely dangerous, so the machine came with a program to keep exposure strictly limited. This program came with a manual to ensure that the operator knew how to handle any issues. Unfortunately, the manual was apparently “written by someone with no knowledge of how communication works.” The “nonsensical word salad” was completely confusing to doctors, so they basically ignored it. When error messages popped up on the Therac-25, they just did what they thought was best. They ended up blasting patients with up to 100 times more radiation than is considered safe. Three died. For 12 hours on April 5, 2006, an Alitalia business class fare from Toronto to Cyprus was listed as $39 instead of the usual $3900. Someone at farecompare.com posted the news online, starting a buying stampede that lasted until the fare was corrected. Alitalia initially tried to cancel the already issued tickets but eventually relented, and approximately 2000 people flew to Cyprus for under $200, including taxes In early 2009, an Oregon company had to place a rush order for new packaging for its Peace Cereal. It seems a typo on the box sent callers to a phone sex line instead of the cereal maker’s 800 number. So, instead of reaching the Golden Temple consumer relations department, callers were greeted by a recorded voice asking, “Do you love sex?” A spokesperson for the company attributed the incident to human error In 2005, a typo by a Japanese stock trader cost one investment bank $224M. The broker meant to sell 1 share of J-Com at 610,000 yen, not 610,000 shares at 1 yen each In 1991, a single mistyped character in a line of computer code left 12 million people without telephone service. DSC Communications and Bell Systems confirmed that massive outages on the East and West Coasts could be traced back to that one, tiny error On August 14, 2003, a misplaced character buried deep in an Ohio power plant’s XA-21 energy management system began a cascade of glitches that rippled across the NE US and into Canada. Within hours, other power stations were failing, and entire cities were going dark, including New York City. In the end, over 50 million people were left without power, communication, and infrastructure for about 7 hours. To make matters worse, the whole thing could have been avoided if one power plant employee hadn’t turned off an alarm. When the initial glitch appeared, the error alarm was disabled while it was “fixed.” The alarm was never turned back on, meaning when the bug acted up again, it remained hidden until it was too late On July 22, 1962, the Mariner 1 space probe was launched from Cape Canaveral for its journey to Venus. Shortly after liftoff, however, it became clear that something was wrong. The rocket carrying the probe began to veer off course, putting it into a path that would carry it not only to a crash landing, but one in a populated area. With no other choice, NASA officials sent a self-destruct signal, destroying the probe and spreading debris across several states.  While coding the spacecraft’s guidance system, a programmer forgot a single hyphen, causing the $80M project to literally go up in flames before it even left the atmosphere On October 8, 2013, President Obama’s senior advisor for strategy and communications, Dan Pfeiffer, was discussing politics with a few of his Twitter followers. After a few tweets back and forth about political polarization, Pfeiffer intended to respond with “also a much bigger factor on the right.” Unfortunately, his errant finger found not the “b” key, but its neighbor “n,” as he spelled “bigger.” He didn’t catch it before sending it to his followers, but he was quick to point out that it was “obviously a horrendous typo.” In 1870, German chemist Erich von Wolf was researching the nutritional benefits of different foods, including spinach. While testing for iron content, he mistakenly placed the decimal point for spinach one spot too far to the right. This meant that the vegetable’s 3.5 grams was inflated to 35 grams. Wolf’s mistake was taken as fact until 1937, when the mistake was discovered and attempts were made to correct public opinion. But by then, the popularity of spinach-munching Popeye had solidified its undeserved reputation In 2013, the Vatican wanted to commemorate the beginning of Pope Francis’ papacy with a big, bold gesture, so they commissioned a series of gold, silver, and bronze medals from the Italian Mint. These tokens featured an image of Jesus with a Latin phrase that the new Pope found particularly inspirational. They were then sold at the Vatican Publishing House in St. Peter’s Square. However, thousands of holy tokens rolled off the line with Christianity’s most revered figure’s name spelled “Lesus.” However, only four were purchased before the rest of the batch was yanked In 1997, Larry Page was in his office at the Gates Computer Science Building at Stanford University with several graduate students, including Sean Anderson. They were having a brainstorming session to think of a name for a website where immense amounts of data would be indexed. Sean suggested “googolplex,” and Larry shortened it to “googol.” Sean immediately ran a domain name search, but mistakenly typed in “google,” which was available. Larry liked the name and within hours he took the step of registering google.com for himself and Sergey Brin That wasn’t Google’s last fuck up! While updating a list of harmful sites on January 31, 2009, one employee accidentally listed “/” as a malicious site, which would be blocked by Google. Since nearly every web address contains a slash, the entire internet came to a halt for about an hour as Google prevented access to every single website. Visitors were turned away with a warning screen, and a complete block page if they continued anyway History of the holiday According to whatnationaldayisit.com, the first detection of National Typo Day occurred on April 6th 2015, but it seems that that may be an error from the algorithm, since National No Typo Day was also first detected on April 6th, 2015 and is actually celebrated on April 6th each year. I searched the hashtag #nationaltypoday on Twitter, and found it in Tweets attached to numerous different dates, including 1/22, 1/28, 3/7, 3/27, 9/9, 6/21, 10/28, 10/17, 11/17, among many many others. Couldn’t find a single one for 9/24 One other social media mention I found was a Facebook post from Gannon’s Gourmet, a family-owned and operated restaurant and catering business in Allentown, Pennsylvania. The post was dated January 29, 2013, and stated, “Today is national typo day so if you are grammaticallyincorrect [sic] you get a free pass. Apple is set to release a 128 gb. Apple ipad 4th. Gen with retina display. Our page would look so good on it. Oh did you know our chicken products are all made with white chicken meat. We focus primarily on the breast for perfect tenderness. Quality produce for you keeps us in business. Thank you all for your continued interest and support. See you at the show….” The post has one comment, from the Gannon’s Gourmet page, saying, “The release date is said to be around feb 5th and geared toward business solutions.” In short, I think Typo Day may be a typo Activities to celebrate Use #NationalTypoDay on social media Visit Gannon’s Gourmet in Allentown PA to enjoy some of their specialties such as their famous “Mom’s Potato Salad”, “Irene’s Tuna Salad”, or a harvest pasta salad with balsamic vinaigrette, all of which are made with NO PRESERVATIVES! Take a typing class? As with every episode, you should celebrate NATIONAL TYPO DAY with our custom mixtape, which I will now present to you in the form of a novel synopsis. This is an age-old story of love, betrayal, loss, and inevitable nihilism from never learning from our fucking mistakes.

Louis Bertrand is a long time resident of Durham Region, east of Toronto, home to 9 currently working CANDU reactors. His background is electrical engineering, specializing in electronics and firmware, the software that gives electronic devices their smarts. He currently is a full time professor in the School of Science and Engineering Technology at Durham College, in Oshawa. He will be presenting as an intervenor at the public hearings for the Pickering nuclear station re-licensing application.             Tuesday is Rally Day! 12:30-1:30 approximately. Whenever the lunch break is called for by Mr. Binder, head of the hearing tribunal   promotes safer and cleaner alternatives to generation by fission or by combustion. They have commissioned studies into the effects of a Fukushima scale accident at the Pickering site, as well as studies challenging the accepted notions about nuclear power in Ontario.    Dr. Nancy Leveson has studied software safety and proposes an approach informed by system science to analyze the root causes of accidents, and hopefully prevent them. Of particular interest is her analysis of the fatal overdoses by the Therac-25, a radiation therapy machine produced in the 1980s by Atomic Energy of Canada Ltd. (AECL). Even if you don’t follow the details of the software flaws, the story is quite dramatic. This was a wake-up call to the medical industry that software safety cannot be analyzed the same as hardware - scroll to the bottom of the page and look for The Therac-25 Accidents. The other popular paper is “High Pressure Steam Engines and Computer Software”, making the point that technology often moves ahead faster than scientific understanding, and bad things happen.   Dr. John Downer - Managing the credibility of nuclear reliability assessment in the wake of disaster And - On the institutional invisibility of nuclear disaster  Charles Perrow made a career of explaining why catastrophic accidents like airliner crashes and nuclear plant meltdowns should be considered normal. The following two articles in the Bulletin of the Atomic Scientists are a harsh look at the denial surrounding Fukushima and the nuclear industry in general - From Hiroshima to Fukushima  And   Email Louis Bertrand - louis@bertrandtech.ca

Set in and around the Princess Margaret Hospital, the story of Alan and Moira exposes the harsh realities of the solitude and fears that accompany cancer treatment with brutal honesty and wry humour. Pettle’s writing comes from a place of awful familiarity, as he explains in his forward, "It’s July 15, 1995, and I’m back in the hospital - radioactive iodine therapy, cancer treatment’s answer to solitary confinement. Why did I write this play? I wrote it to survive days like this. [...] I wrote it not only for those who have passed on to other journeys, but for all those who remain in Therac corridors everywhere. People that are not just statistics in flimsy pamphlets or black numbers on manila envelopes, but individuals with brilliant minds and raging spirits, with awe-inspiring courage and beautiful children."It was the personal connection to this story that brought this production into existence and provides the motivation to engage in the realities of the content beyond the story-telling. As well as donating a percentage of both the ticket proceeds and additional fundraising efforts to the Princess Margaret Cancer Foundation and Gilda’s Club Greater Toronto , the production is coordinating with several organizations to provide talk-back opportunities and other activities in support of the individuals and families fighting the disease both known and unknown to us.Cass Van Wyck: Twitter: @classvanwyck Instagram: classvanwyckJessie Fraser: Instagram: slackbabyChristopher Lewis:http://www.majorcallisto.com/ Instagram: majorcallistoTickets: https://www.brownpapertickets.com/event/3373355 Facebook: https://www.facebook.com/events/1886254528331793/
