Every comic is really a frustrated rock star.

Being onstage is like being rock star. Whereas if you're doing a movie, it's such a confined space. You know, you do a comedy, it's so hard, too, 'cause with a comedy, there's no vocal reaction, there's no energy that you get back that spurs you on to be funnier because everyone has to be quiet.

I'm not a giant rock star. I play one on TV, though.

You know, I always root for the older athlete. I root for the second album. I root for solo careers after the rock star breaks the band apart.

My musical background is like almost every non classical musician in the world. One day a special record was heard and that was it. I was hooked, started trying to play various instruments and was off to bar land to become a rock star. What else?

Before, models had that rock star life and it was all about going to the parties and having that glamorous life, and I think these days, models are more like businesswomen and the whole industry takes it really serious.

I'm not someone who gets to play The O2 and places like that, but that's the kind of rock and roll venue. The popularity of stand-up means that some people are getting to play rock star venues.

So you know, my plan was that I was going to make records, and be a rock star. And that's really what I wanted to do. And I sang from the time I was very young.

What makes you a rock star is what are you able to do when you get behind that microphone, when you put that guitar in your hands, when you wield those drumsticks, and when you raise your hand in front of twenty thousand people: do they respond? That's being a rock star.

If I'd been a rock star, I'd probably now be dead.

I wanted to be a rock star.

When I started out, I wanted to be Billy Joel. The plan was to be a singer-songwriter of that ilk, and, then, I got waylaid - that's probably an unfair way to say it - from being a rock star by the musical theatre stuff, which I love doing.

Daniel Ek, the C.E.O. of Spotify, is a rock star of the tech world, but he is not long on charisma.

I would have wanted to be a rock star, a lead singer, if I wasn't a model. I'd go touring in a bus with my band. In my next life, that's the plan.

Now I know what it's like to be a rock star. No, I didn't sleep with 5 groupies at once. But I was interviewed about 45 times in 5 days in 3 cities.

If you're going to pretend to be somebody you're not - which is the whole point of being a rock star - then why not just invent fake characters and have them do it all for you?

I never really felt like a rock singer or a rock star or whatever.

Everybody has terrible things that they deal with. Everybody. Just because you're some big shot rock star doesn't mean you're immune to having these awful tragedies in your life.

When I started out, I wanted to be Billy Joel. The plan was to be a singer-songwriter of that ilk, and, then, I got waylaid - that's probably an unfair way to say it - from being a rock star by the musical theatre stuff, which I love doing.

In some ways, I always thought you're better off behaving like a rock star when you're a normal person. Because if you do it as a rock star, you'll end up in the papers and your life will be made a misery.
