Unseen sketches from Monty Python have reportedly been discovered in the archives of Michael Palin.

The comedy group – featuring Palin, John Cleese, Terry Gilliam, Eric Idle, Terry Jones and the late Graham Chapman – produced their last film 35 years ago but boxes of material have now emerged, according to The Times newspaper in London.

The material was deposited at the British Library last year and contains unused script ideas, including two sketches written for Monty Python And The Holy Grail.

One of the sketches is about a Wild West bookshop while another features an “amorous Pink Knight” – potentially as amusing as the now legendary Black Knight who refuses to yield to Chapman’s King Arthur.

The new scripts will go on display to the public along with more than 50 notebooks containing notes on two of the Pythons’ films, Holy Grail and Life Of Brian.

Material deemed controversial at the time was discarded and would even be seen as too risque today, according to the newspaper.

Palin, 75, has given permission for the sketches to be reproduced and admitted the group often produced more material than was needed.

“Sometimes you have things like that. I can’t think why it wasn’t used,” he said.

“The Holy Grail took shape gradually and at the beginning it had far more ideas in it than ended up on screen because you had to have a narrative. In the end the story of the knights was strong enough.”

The material was donated to the British Library by Palin last year.
