I think we have responsibilities to be active in the things we believe in, regardless of what our job is. At least in my lifetime, there has been a tremendous combining of activism and music, that came up in the era of Pete Seeger and the Weavers and Joan Baez and Bob Dylan and Peter Paul & Mary.

A lot of political music to me can be rather pedantic and corny, and when it's done right - like Bruce Springsteen or Jackson Browne or great satire from Randy Newman, there's nothing better.

I don't want to sound like a self-help book, but it really has been transformative for me to take a look at my relationships in a new way and see my part in them. Everybody's going through that.

AC/DC's 'Highway to Hell' is the greatest meshing of vocal, guitar, and content I've ever heard. That's what I aspire to.

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 one of those people who just doesn't plan my personal life. I plan my professional life.

I don't think there's ever been any music quite like what we came up with.
