You might have thought with the Anthology albums and those half-arsed bits of old song that were made into a "new" Beatles record, the world already had everything the Beatles had ever recorded, plus a spot of stuff they never did.
There is, however, one outstanding piece of tape: Carnival Of Light, which was really a McCartney solo piece with the rest of the group noodling about banging stuff. Like a Beatles with three Ringos.
Inevitably, though, even this must now be dragged out and given a proper release:
'I like it because it's the Beatles free, going off piste.'
Although not "free" as in the sense of he's going to give it away. He's got an expensive ex-wife to support, you know.
