The material, deposited at the British Library in 2017, has been revealed to contain unused script ideas including two sketches written for Monty Python and the Holy Grail.
Unseen sketches from Monty Python have been discovered in the archives of Michael Palin.
One of the sketches is about a Wild West bookshop while another features an “amorous Pink Knight”.
Palin, 75, has given permission for the sketches to be reproduced and admitted the group often produced more material than was needed.
