When, in 1966, I progressed to The Frost Report, I was paid ten guineas a minute. I was guaranteed three minutes a week, so this was good money.

I used to have a house in London, but couldn't face 20 more years of St John's Wood in the rain.

I always have a feeling you should move the playing field and the minute you know what you're doing, you're wrong. Therefore, I wanted us not to try to follow Spamalot immediately, but to do something different. This is perfect because it uses all the same skills, like story telling and lyric writing and music writing, but it's presenting it in a different form. And of course it gives me and John a nice chance to perform and show off which is also fun.

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.

No day of my life passes without someone saying the words 'Monty Python' to me. It's not bad.

The idea that we evolved with these thoughts is actually very fascinating - to me.

Bear in mind the simple rule, X squared to the power of two minus five over the seven point eight three times nineteen is approximately equal to the cube root of MCC squared divided by X minus a quarter of a third percent. Keep that in mind, and you can't go very far wrong.
