There are 'bootlegs' of Bowie's early pre-fame acoustic demos available - many on youtube..

which positioned his aspirations on the fringes of commercial 'Simon & Garfunkel' harmony soft folk rock.

crackly distorted tapes & acetates.. shame some were never released properly.
I have a soft spot for his 1960s recordings.

All us teen fans probably got suckered by that Decca "World of David Bowie" LP with the ziggy cover photo.
But I genuinely enjoyed it and sought out the expensive expanded double LP...
