I have been to over 200 shows and the worst by far was Prince. This was about 6 years ago and it was VERY dissapointing. I was and still am a huge fan, but he SUCKED on this night. He played ZERO of his hits, the stage was boring, he rarely spoke to the crowd and all he did was play extended jams. It seemed more like a rehearsal. People were very pissed afte the show, many of them booing. There was no electricity at all.
Saw him last month and he was great.
