a short answer is
MostOR THE MAJORITY OF N/SOUL records come in both issues and demos
however some smaller labels may only have ever put a record on to demo/promo and not issued them at all.Or in this case demos have been found but very few Issues are known to exist obviously due to its commercial failure.
there are numerous N/Soul tracks which have the same plight
demo being the most common version..issues rarer.
But not every record is rarer on issue than demo..It works both ways.This just so happens to be
ONE OF THE RARE ISSUES...RARELY SEEN COMPARED TO THE AMOUNT OF DEMOS
WHICH TOO ARE GENUINELY RARE.
HOPE THIS HELPS,,,THE GASHER
