Friend of mine claims that back in their hey-day, he was at a bar on route 20 when the Stones were playing Rich Stadium. Show was sold out, so he didn't make it. Bout an hour and a half after the show was over, a guy walked in, and told the bartender to lock the doors, nobody comes in, anybody that's here can stay, but can't get back in if they leave. Then the Stones come in and just jam for like two hours. Also allegedly had a hefty tab that they stiffed too.
