You've been on stage for 40 years, is there an impetus to stay relevant? do you listen to rock today? If you look at the bands that are still here from the 60s - Bowie, Elton John, Alice Cooper - we're all still working, we're all still touring. I think I'm doing some of the best shows I've ever done. I don't think what we do is disposable. My generation seems to have a different work ethic. I always thought, "Do 25 albums." I'm a lifer. A lot of bands today get together, play, make an album, break up and form another band. There's no bands staying together.
