I'd always suspected it was actually a GP set and have seen it as GP 28th Nov before but Al claims he has got the original Sasha tape in that tracklist thread. Is your tape an original from Parky at the Hac as you said for one of the other sets you up'd? If so I'm guessing that tape was sold falsely as Sasha (as happend with loads of Vertigo tapes). :S
There's a Mike Pickering KAOS tape i have which I also reckon is GP Nov '92 after looking through it yesterday....
