Paul McCartney — “Psychedelic” Beatles track to be released?

From RS:

In an interview with BBC Radio 4, Paul McCartney revealed that he is trying to release a Beatles song that some swore didn’t exist. “Carnival of Light” is supposedly a 14-minute improvised psychedelic jam the band recorded in 1967 and was left off of the Anthology releases because it was “too adventurous.” “The time has come for its moment,” said McCartney, who is looking into getting approval from Ringo Starr and the estates of John Lennon and George Harrison to release the track. “I like it because it’s like the Beatles free.” McCartney didn’t provide a time frame for the song’s release or whether it would be included on a compilation or exist as a stand-alone song.
