What is this, so we aren't allowed to comment on his rude, bad behavior without being called hysterical? He is filthy rich, yet can't bother to do his own job properly: show up at a concert in time. And when he does, he doesn't bother with apologies, until he hears that the press has caught on his lacking interest in performing.
He is no victim here. If the going is getting too tough for him, he can always take a break. But he won't because he likes the perks of the job. Well, they come with the downside as well, like showing up to is own concerts on time, being professional, acting like a grown up. There are many others who have been in the business from the same age he has, and they actually manage to be professionals.
