Absolutely everybody had a great time at the festival. The bands loved playing to a crowd that big. The audience loved being played to. The revelers loved being in a huge open community where sex and drugs circulated freely, and nobody wanted to start any trouble. It was the Summer of Love and three days of absolute bliss, where the party never stopped, and nobody went to bed. The only people not enjoying a second of it were the organizers.
As we already know, nobody paid to get in. That means there was no money to pay the bands. Some of the acts, aware of the problem, demanded to be paid in cash before taking the stage. This meant the organizers had to persuade a local bank to open on a Saturday - unheard of at the time - and allow them to withdraw money and pay their performers. If they hadn't have done, the festival would likely have become a complete bust.
