Michael Palin has declared that much of Monty Python's material was "crap."

In an interview with The Daily Telegraph, he said: "People forgive you the things that don't work. A lot of Python was crap, it really was. We put stuff in there that was not really that good, but fortunately there were a couple of gleaming things that everyone remembers while they've forgotten the dross."

The legendary Python team are currently rehearsing for their 10 sold-out nights at London's O2 arena in July and Palin says the new stage show will be a comic extravaganza.

"We've got dancers, we've got songs, things that have to take place while we're all off doing our changes," he said. "We're all playing about ten different characters, and it takes time to change when you're seventy-three."

The Pythons have ruled out touring their comeback show. Palin, however, has announced his own solo tour in September, to accompany the publication of Travelling to Work 1988-1998, the third volume of his diaries.

The book covers his time making the hugely popular travel documentaries Around the World in 80 Days and Pole to Pole.

"When I was young. I remember thinking 'one day I'll become an adult' and I'd become rather serious and wear a tie and go to cocktail parties," he said at the launch of the tour at the London Book Fair. "But I realised that's not really what it's about. It's about a state of mind. And I've never really, properly become an adult."
