He mentioned this sort of thing in an interview.
“I do expect etiquette inside of the theater, the same way you would at a Broadway show,” he says. “My shows are not really concerts anymore. They’re performances, and there’s a difference between a performance and a concert. Look, I’m not for everyone anymore. I’m just not. And if you want to come and scream and yell and get drunk, don’t come to my show.”
Having seen him, I'd agree. His band is one fine outfit, his shows are long and impressive. They leave it all on the stage.
