I have a friend who attended the show so I know the part about them singing Wanted and the crowd going with it and that much of the audience walked out after Bon Jovi is true b/c of her telling me about the show. Jon talked about the hissy fit Billy Joe had (in his ever so diplomatic Jon could be a politician way) on MTV. I have a video clip where he was asked about it and he commented, basically laughed it off as no big deal.
