Come to think of it, I do remember hearing about this now that my memory has been jogged. The unique 2-disc set by John Oswald first saw the light of day in November '95 and had a tenth anniversary reissue too, which is probably when I read about it here at the board. "Plunderphonics" did ring a bell deep in the recesses, you understand.
Boy, this sure makes my share look like crap.
