Paul McCartney says it's time an experimental Beatles track saw the light of
day.

McCartney says he wants to release "Carnival of Light," a 14-minute
experimental track the Fab Four recorded in 1967 but never released.

The band played the recording for an audience just once, at an electronic
music festival in London. It reportedly includes distorted guitar, organ
sounds, gargling and shouts of "Barcelona!" and "Are you all right?" from
McCartney and John Lennon.

McCartney said during a recording session at Abbey Road studios he asked the
other members of the band to "just wander round all of the stuff and bang
it, shout, play it. It doesn't need to make any sense."

"I like it because it's The Beatles free, going off piste," he told the BBC
in a radio interview to be broadcast Thursday. Extracts of the interview
were published Sunday in The Observer newspaper.

McCartney said he still had a master tape of the piece and "the time has
come for it to get its moment."

McCartney, usually regarded as the most melodically minded Beatle, told the
BBC he had a long-standing interest in avant-garde music. He said "Carnival
of Light" was inspired by experimental composers John Cage and Karlheinz
Stockhausen.

He said he had wanted to include the track on the Beatles' "Anthology"
compilation, but was vetoed by his band mates.

McCartney would need permission from Ringo Starr and the widows of Lennon
and George Harrison to release the track.
