Is that what the kids are calling it these days?
In all seriousness, I once saw 10's of thousands of people walk out as soon as Elton John started his gig. It was the Harley Davidson 100th Anniversary celebration in 2003 and over half the crowd left as soon as the "surprise headliner" was revealed. I must admit, HD did not think it through when they put a gay English knight on the stage for their crowd (and did not tell anyone prior to the show) at their centennial celebration. I have heard that Willie G Davidson's daughter was in charge of the acts for the final hoorah, and she was a huge Elton fan. I was psyched as I and my friends were able to easily move forward about 100 yards.
