When I do my solo concerts, I'm used to being on the stage for two hours solid, singing 16 songs. And when I did 'Funny Thing,' I was on the stage the whole time. This is much more difficult. It's the difference between racing and sprinting. This is sprinting. And I have to learn to pace myself.

And singing is a physical thing - your vocal cords are these muscles.

My influences were Little Richard and Jerry Lee Lewis and Chuck Berry.

When my 'Scientific American' arrives every month, I read it cover to cover.

Is there a God? No. God is a verb, not a noun.

My parents were both in show business. My father was an actor, my mom an actress, and both singers, dancers and actors. They met in Los Angeles doing a play together and so I grew up in a show biz family.

The thing is, I'm not a prolific songwriter.
