Don’t talk about drinking and hunting. Don’t be yourself. Just sing your damn songs — and leave.

After the warning, the artist decides:

I am a damn country singer playing Wrigley freakin’ Field. And, damn, I’m nervous. I drag my big ass all the way up here to Chicago for two reasons — to play country music and to drink.
