I guess they don't think it's appropriate for children, but I don't think rock shows should be for children. I guess there's a difference between our fans and Good Charlotte fans. Theirs might be younger. They may not be prepared for the real world.
I think if you're in a band it's necessary that occasionally you do things that aren't self-serving. Just take a bit of your time and do something other than trashing a hotel room.
I don't think too many things go out of style. They just start to suck, like bands.
