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.

Toward the later days of Sabbath, instead of going in and knocking out what songs we did in rehearsal, we would polish them to death.

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

The Geezer album, Black Science, had a lot of keyboards and it did not work.

If you are a pop band, don't say you're a metal band. Poison and Warrant were about as metal as the Backstreet Boys.

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.

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