"Carnival of Light" -- a 14-minute experimental track recorded at the height of the Beatles' musical experimentations with psychedelia and inspired by avant-garde composers such as Karlheinz Stockhausen -- has long been considered too adventurous for mainstream audiences.
In an interview for BBC radio, McCartney said his bandmates and their producer George Martin had vetoed its inclusion on the exhaustive 1990s "Anthology" collection, according to UK's The Observer newspaper.
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.
This would be AMAZING. The great thing about the Beatles is that, no matter how many times you listen to them, they still have the potential to sound fresh, modern and innovative. They are one-of-a-kind in that regard.
