To do the Ozzfest again would be great. I'd like to finish with a final Sabbath album. You always feel that it is still a challenge.

When you see all of these bands citing you as influences, it makes you feel relevant

Jack Bruce, as soon as I saw him, it changed me. I didn't even know what bass players did until I saw Cream.

Without a doubt, Ozzy is the craziest person I've ever met. Son of Sam is a close second.

Black Sabbath was written on bass: I just walked into the studio and went, bah, bah, bah, and everybody joined in and we just did it.

I never picked a bass up before Sabbath started

To me, Sabbath was always just a really heavy blues band. That s all we were. We just took those blues roots and made them heavier.
