This is the Beatles project that documents the group falling apart better than any other. There had been tension the year before during 'The White Album' sessions, and there would be strange, weary resignation during 'Abbey Road', yet somehow it didn't show itself on those records. With 'Let It Be', we had the movie as well, so we could see how tired and sometimes bored the group looked, and the long, unwilling sessions that eventually yielded this album.
John only wanted to be with Yoko ; George got pissed off with Paul again, and Ringo patiently tried to do his job. When they heard what they had recorded, they shelved it. So what we finally got was Phil Spector's weird mish-mash of 'live and raw but with strings and choirs dubbed on'.
Many years later, with the benefit of today's technology, the album was scrubbed down, finally resequenced to sound like an album, shorn of a few bits of chat and throwaway jams and released as 'Let It Be Naked'. And for me, that's the one to go for.
