The one thing about the music business is that there is no rulebook. It's not like the NFL or something where there's four downs to get ten yards or baseball where it's three strikes and you're out.

As much as I love heavy riffs, I like The Eagles, Neil Young, Elton John, Crowded House.

You're never going to learn everything.

On the tour we get a case of beer on the bus every day from Ozzfest.

If I'm playing with Ozzy it's just a guitar thing. But with the vocals I feel like I'm studying for the SATs.

I'm a good Catholic boy.

There's only one Sabbath guitarist and he is the architect for everything, Tony Iommi.
