a friend had a boot of the (partial ?) sessions from let it be...
it was, if i remember, 4 (or more ?) albums (vinyl) and some of it was nothing but studio noise, with someone or other practising/playing/doodling about off mic nearby - you had to strain to hear much, but it was there...
some of it was front and center, some arguing, some playing around w/lyrics...the thing i remember most was a version or 2 of pauls 'no more pakistanis'..and george doodling about with some music, w/ either john or paul asking what it was,
all in all, one could've edited it down to a 1 or 2 cd and had all the pertinent bits, but, if i remember correctly, this was only part of a set...so there could, and may be, quite a bit out there...somewhere
i do remember comparing notes when the anthology came out..and there were a few bits there from those sessions
everybody bogey...dig that bogey beat...man, that bogey rhythm...smells so clean 'n sweet
everybody bogey...bogey onto the streets...without bogey music...life is incomplete
