Playing guitar was one of my childhood hobbies, and I had played a little at school and at camp. My parents would drag me out to perform for my family, like all parents do, but it was a hobby - nothing more.

Pat Benatar might need a rock band, but I can just sit with a blues guitar for an hour and a half and do folk songs and great contemporary ballads, and not many people can pull that off.

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.

Distribution has really changed. You can make a record with a laptop in the morning and have it up on YouTube in the afternoon and be a star overnight. The talent on YouTube is incredible, and it can spread like wildfire. The downside is that it's very hard to convince the younger generation that they should pay for music.

I would love to see a revival of what we had against the war in the '60s - we could do these teach-ins on the internet, live and split screen, and have real in-depth debate between people that are on the "other" side of issues - nuclear, gun control, whatever. We could really be having a much more democratically involved and exciting debate with people emailing their questions and having a virtual town meeting.

I think I'm a living embodiment of, 'Don't try to push me around or squash me,' whether its how I talk to a record label or in my relationships.

I'm the same on stage as I am off stage. A lot of people who I admire - Bruce Springsteen, Jackson Browne - are not that different either. You hope that if you met them that they'd be as nice and well-rounded as they appear.
