I do sing about drinking, but it's in a party way. I don't sing about drinking in a drowning-my-sorrows way, like in George Jones's "If Drinking Don't Kill Me (Her Memory Will)."
When I started playing music at East Tennessee State University I would sit on a stool with a tip jar in front of me and play four hours a night at a college bar called Quarterback's Barbecue. I wasn't thinking about doing it for a living. I was just making enough money to go to Taco Bell every day. People were eating chips, drinking beer and not listening to me. I'd had three or four years of people ignoring me, and I'd kind of gotten used to it.
I don't really drink before a show. That's my only drinking rule. Especially with today's cell-phone cameras, there's no win to it.
