Q: Was that feeling there when you first met her?
A: Well, I thought she was a beautiful girl. I had no idea that she was that young. When I found out how old she was, I said, “You know what? Wait till you get out of college, and then we’ll talk.” She was 21. Basically we just talked to each other for a long time. We had a lot of phone conversations, and it developed that we just really liked each other, aside from chemistry. We joke about it. I mean, being a rock-and-roll star, you’re supposed to be immature. And certain aspects of my personality are immature. I just have this young, teenage way of thinking about the world and life. Let’s face it, women are five to 10 years more mature than a man their own age anyway—so you start with that premise. Now, she’s very mature for her age anyway, and I’m immature for my age, so we kind of meet in the middle. Sometimes she’s older than I am.

Q: Are you interested in having kids again?
A: Yeah. We might. That’s something between me and her, though. I mean, we’ve talked about it. But she’s trying to establish her own identity. She wants to feel that she’s accomplished something in her life. She doesn’t just want to be Billy Joel’s wife and sit around and eat bonbons.

Q: Of course not—she’s published a cookbook and was the original host of Top Chef, right?
A: Yeah, that’s her love. And I encourage her to do that. I’m actually very proud of her for doing that. She doesn’t just sit around and spend my money.

Q: In person, you crack a lot of jokes about your appearance.
A: Well, I don’t think I look like a rock-and-roll star. I mean, I look like the guy who makes pizza. I’m not really insecure about it. I just think it’s kind of funny. I see pictures of me and I go, “Good God, that doesn’t look like a rock star.” There’s a weird juxtaposition about the whole thing. People are coming to see me. Women are writhing and screaming in the front rows. And I look up on the screen and I see this funny-looking guy.

Q: In high school you took boxing lessons and won a number of amateur bouts.
A: I started boxing because I used to get picked on. I was a small guy, and I would walk down the street to take piano lessons and I’d get picked on—they’d knock the books out of my hands and they’d smack me. I said, “I’m sick of this.” I didn’t have a dad around, so it was kind of a way of finding my own manhood, I suppose. I learned how to box at the police boys’ club, and I kind of liked it. I suppose when you’re a teenager you’ve got a lot of hostility, and that’s a way to get rid of a lot of it. I boxed for three years and I won a good amount of fights, but my last fight, even though I was a better boxer than the guy I was boxing, he was just so big and he was made out of rubber—I couldn’t hurt him. And he broke my nose. It was part of finding my own identity when I was a teenager. I found out that it’s not about how hard you can hit. It’s about how hard a hit you can take.
