The 14-minute long Beatles recording, "Carnival of Light," will finally be released, after 41 years.

How bad can it be?

... distorted guitars and drum-beats, gargling, church organs, and Sir Paul and John Lennon yelling: "Are you all right?" and "Barcelona!"...

"I said to the guys, this is a bit indulgent, but would you mind giving me 10 minutes? All I want you to do is just wander round all the stuff and bang it, shout, play it. Then we put a bit of echo on it. It's very free."...

The producer who oversaw the recording, Sir George Martin, described the track as "a kind of uncomposed free-for-all melange of sound".
