When I was 18 years old, I went on the road with my dad after I graduated from high school. And we were riding on the tour bus one day, kind of rolling through the South, and he mentioned a song. We started talking about songs, and he mentioned one, and I said I don't know that one. And he mentioned another. I said I don't know that one either, Dad, and he became very alarmed that I didn't know what he considered my own musical genealogy.
