Or a 'cunt' in robyyk1's thread
maybe commix - painted smile?
To be honest, I think the fact that there was a ten minute version should be a big big clue... there's not that many producers making tunes that long. I probably haven't been around long enough to know it but I reckon somebody would.
Could it be this one?
According to discogs, the album version is 13 minutes long, so maybe that's the tune you're looking for?
