Singer Pete Doherty has recorded an exclusive track for a documentary about his comic idol Tony Hancock.
Pete Doherty was a member of the Libertines until they split in 2004
The song Don't Fall Backwards refers to a book Hancock read in a Hancock's Half Hour called The Missing Page.
The Babyshambles star said: "I don't know whether it's possible to be nostalgic for a time that didn't exist, but I think I am."
He is also interviewed in the 90-minute BBC Two documentary The Unknown Hancock which will be screened on Boxing Day,
