Yikes Billie Joe certainly got mad there, huh?? And while I don't necessarily condone temper tantrums, I do agree with his overall point that Green Day's been around for far too long for them to be getting their set cut short at a festival.
he was mad from the beginning because the crowd was dull, then they started cheering for Usher, that's when he really got mad. the event coordinators didn't help matters by showing him the time.
