"I enjoy writing songs that could have been written before [my time]. When I feel like I'm tapping into a deep vein in the body of American music, it gives me strength as a writer, like I'm dipping my pen into a deep ink well. That's the folk music tradition. Like Pete Seeger said, 'Everyone's a link in the chain.' It's a strong chain, so rely on it. ... I believe it takes all those great songs in the past to make your song even a little bit good."
