I'd also be interested in more info on this record....I posted it as a possible contender in the thread entitled 'The bootleg that everybody sells as an original'....here's what I posted...
"Apparently, on the Solid Smoke LP which includes the above track Ollie McLaughlin writes in the liner notes that this was never released?
Don't have the LP to quote exact comment, but could this be the (bootleg) 45 in question.....?"
Mace's post in Volumes - Ain't Gonna Give You Up was marked as the answer
