Zac Brown wants to make sure his fans get their money’s worth when they see him in concert, so he forbids his crew from getting sloppy drunk.

He says: “I put a rule down about seven years ago that nobody could drink before or during the show. So our whole crew of 105 people out on the road; nobody’s allowed to drink or party or do anything until after the show’s over. Because there’s nothing worse than spending a bunch of money to go to a concert and you see a dude that’s half-drunk on stage.”
