“If those tracks have not been released in the past fifty years there must be a reason...applying Occam’s Razor...probably they’re just crap (of interest only to dedicated collectors).”
Sometime in the 70’s there was a bootleg album of the Get Back studio sessions that was just a bunch of noodling on instruments and talking.
Yeah, they mystic pull of bootlegs... Somewhere in my LP collection there rests a bootleg double LP of Pink Floyd live at Pompeii (IIRC). Ostensibly recorded with one of those early Walkman-type devices appr. 500 yards removed from the stage - mostly one hears the surrounding fans mumbling in their drug-induced stupor. Yet someone actually thought it was a good idea to press vinyl LPs(!) from that...err...recording effort. (And the cover art is to die for..LOL) Hey, only 5 bucks from the flea market. No great loss.
