On the 3rd of December, 1979, English rock band The Who were scheduled to play a concert at the Riverfront Coliseum in Cincinnati, Ohio. Thousands of general admission ticketholders gathered outside the venue hours before the scheduled start of the concert… but were kept waiting outside by organisers while final arrangements were made for the night’s performance. When the go ahead was finally given to let the waiting crowd inside, only two doors were opened. Two doors for more than 8,000 people. By the time The Who actually did take to the stage that evening 11 of their fans would be dead.
