Beatles unreleased Carnival of Light to see the light of day?

I think Paul McCartney occasionally brings such things up for the sake of publicity (in this case, the release of a new electronica album under his "Fireman" moniker) without having any concrete plans to follow through, but he's saying that, maybe, we'll finally be able to hear the Beatles' "Carnival of Light."

The 14-minute experimental track was created for a 1967 "happening" at London's Roundhouse and, frankly, doesn't sound like something you'd want to hear more than once. If that.

The improvised work features distorted electric guitars, discordant sound effects, a church organ and gargling interspersed with McCartney and John Lennon shouting random phrases like "Barcelona" and "Are you all right?"

But, still, it's the Beatles, right?

McCartney confirmed he still owned the master tapes, adding that he suspected "the time has come for it to get its moment," The Observer reported. "I like it because it's the Beatles free, going off piste," McCartney said.

McCartney would need the consent of Lennon's widow, Yoko Ono, and George Harrison's widow, Olivia Harrison, to release the track.

So, don't hold your breath. But, maybe, as part of the long-rumored/promised Beatles remasters that are supposed to start coming out sometime next year, they'll include this as a "bonus" somewhere along the line.
