I don't necessarily know much about comedy, I don't spend a lot of time watching it. Mainly because all my life for about 50 years I've had comedy.

They're a typical Hollywood audience. All the kids are on drugs and all the adults are on roller skates.

To me, the musical is best when it's a musical comedy. So if you have a very, very funny show, and very good, funny songs, that's what the musical does best.

Monty Python paid me £20,000 to write, direct and assemble them - the cheapskates! I told them I'd never earned less in a year since leaving Cambridge. The first show sold out in 43 seconds and we ended up performing ten in total. We had no idea there would be such demand.

Elvis saved my life when I was 13 or 14. He saved all our lives.

I like doing live things and plays. You can perfect the laugh or extend the laugh, you can get them on a roll. Versus improv, which I hate. Put it all together. They're more vignettes. Improv makes me slightly anxious because I feel for them.

Learn to trust yourself. That's very vital. ... Just stand with yourself. Remember, in his lifetime, Van Gogh sold only two paintings. I personally sold even fewer.
