There were so many great music and political scenes going on in the late '60s in Cambridge. The ratio of guys to girls at Harvard was four to one, so all of those things were playing in my mind.

Elvis might have compromised his musical style a bit towards the end, but that doesn't mean that artists from the rock n' roll/folk-roots culture - of which he was not really a part - shouldn't get better as they get older, like the great jazz or blues artists.

I'm glad I get singled out for my slide guitar-playing, which isn't that difficult to do. I didn't take guitar lessons, but I just love the way it sounds, almost like the human voice.

Part of the reason I had such a drive to be an activist, and support other activists, is because I was raised Quaker and my parents kept us very much informed and involved as kids in civil rights and the conservation movement.

How I measure success is getting to make another record and being able to the come back to the same town and play again cause you sold out the last time.

The fifth member of my band is my non-profit work.

I don't go into any album with a concept or a deliberate direction. It's more letting the best music that really appeals to me at the time, the best songs that I find after many months and years of search and sifting through my collection, and asking radio people and journalists. It's really an ongoing search that's as much daunting as it is somewhat exciting.
