Back then, I was really into composing the entire solo, beginning to end. I wanted to have it at least 80 to 90 percent complete before going into the studio. I didn't improvise in the studio. I was young, and I didn't really have the development in my playing or the ability to show up with nothing and then put down 500 ideas. I can do that now because I'm so much more of a musician now.

If there was no Black Sabbath, I could still possibly be a morning newspaper delivery boy. No fun.

Some people try and tell you what the songs are about and it bores me to death.

Metallica's the only band I've ever been in and it's the only band I ever wanna be in.

I really like LIMP BIZKIT. I mean, I've said it for years - I don't know if anyone actually hears it - but I think LIMP BIZKIT are an awesome band. In terms of the rap-rock bands, or ANY bands out there, I think they really are truly among the best.

I would say [Lamar] Kendrick, it`s always fun to see what happens when Kendrick takes the stage. And my two oldest kids are huge fans of him.

Hugh [Evans] called us. And obviously this has been on our radar for all the years it`s been going on. And each year obviously reaches more and more people, and it`s high profile. Hugh reached out to our manager just down the street. And we said we`re here [ on GLOBAL CITIZEN in the Central Park] to help and do whatever we can.
