Previously-unreleased tracks by the Monty Python team have been unearthed from the archives and will be issued this summer, as the comedy troupe celebrate their last hurrah.
The three recordings will be included in a re-released album due to come out next month, Monty Python Sings (Again), and designed to coincide with a series of live shows at the O2 Arena in London to bring down the curtain on their career
The first of them, Lousy Song, was given its premiere on Simon Mayo's show on Radio 2 and posted online.
It was originally recorded during sessions for Python's Contractual Obligation Album in 1980, and was performed by Eric Idle, while the late Graham Chapman continually interrupts to declare how much he dislikes it.
Idle said of the track: "It is the only totally improvised sketch I can remember Python doing. Graham enters the recording studio when I'm listening back to a song I have recorded - I think it is very funny."
The album comes out on June 9, with a box set of all their recordings, Monty Python's Total Rubbish: The Complete Collection, due to come out on June 30.
