Paul McCartney wants to release a 14-minute experimental track recorded by the Beatles 41 years ago for an electronic music festival.

McCartney told BBC radio that the song, "Carnival of Light," was The Beatles at their most free and releasing it would show that the band was working with "really avant-garde stuff."

McCartney had wanted to release the song in the 1990s as part of The Beatles' Anthology compilations, but Ringo Starr, George Harrison and representatives for John Lennon vetoed the idea. He is hoping to get the approval from Starr and the estates of Lennon and Harrison this time around.
