Joan Jett performed and was not treated well - "I Love Rock n Roll" got a little response from the crowd, but she was getting booed near the end of her set and as I recall, she got pretty upset and left the stage.

There was a pretty long wait for Robert Plant (45 minutes?) and then someone came on stage and announced that his drummer had slipped in the shower and broken his wrist. Robert Plant rescheduled the concert for the spring and you could use your ticket stub to get in... Joan Jett wasn't the warm-up band for that one.
