SIR Paul McCartney last night revealed the Beatles were churning out drug induced bollocks at least 18 months before John Lennon got together with Yoko Ono.
Confirming the existence of the improvised track Carnival of Light, Sir Paul said it was inspired by the modernist composers John Cage and Karlheinz Stockhausen, as well as a Tupperware box filled with 'grade-A Jamaican bongo'.
"It's basically 14 minutes of John hitting Ringo with a soup ladle. He managed to produce this lovely warm tone by striking him directly on the top of his head.
"We then mixed it with George chanting a refrain about some fat bird that used to work in a cake shop near the Liver Building. It's really an early version of Pipes of Peace."
The song was recorded at Abbey Road in 1967, but was soon confiscated by prime minister Harold Wilson who would wake up Tory firebrand Enoch Powell in the middle of the night and play it to him down the phone.
Sir Paul said the Beatles performed the song live just once, at a festival in Barcelona, when John Lennon introduced it while doing his tiresome impersonation of Carry On star Sid James.
Beatles experts say the track probably inspired Lennon and Ono to produce the experimental 1968 album Two Virgins, better known by its alternative title, Twelve Rackets.
