Q: What do you think it was that drew people to the Louvin Brothers' music?
Charlie Louvin: I think it was the songs. We sang about life. Life is certainly no bed of roses, and it's not always easy. I don't care if you're rich or poor, or a banker or a bum. Life is not kind to you sometimes.

Some country gospel for your ass.
