I don't really drink, but I've been around a lot of drinking and, at 18, when you start playing in bars, you start to witness the good, the bad and the ugly of alcohol as a source of escape. I wrote about it because I witnessed its use as a means of medicating - a lot of people using it to medicate themselves from hurt.

In retrospect I wrote things about my life and my family's existence, I realized that it was a frighteningly harsh way to make a living. And I used to say that they were slowly dying trying to make a living.

Sadly, I wish I had been able to play ["Miner's Prayer"] for [grandfather]. Yeah, I'll never escape the influence of him in my life. And my - his wife, my grandmother, Earlene Tibbs - those experiences with them shaped me musically probably more profoundly than anything else in my life and shaped me as a writer.

Country music originates with the colloquial, rural aspects of white America. It's really, truly, rural white America's blues.

The future has a lot to do with the past.

I wrote "Miner's Prayer" after [grandfather] died. I'd gone back to his funeral, and he died in 1979. And I came back to California, and I think a couple of weeks after that funeral wrote that song thinking about him, his life.

I was very fortunate in having David Fincher, the director come to me. Now I've seen the finished product, I feel that every bit of the nine months we spent on the film was worth it.
