regarding the Nitzer Ebb track he played, it could be one of those mentioned (I don't know the remixes or the originals) but it could well be something he's put together himself purely for using with Final Scratch, some of his edits for that purpose are wonderfully confusing.
Regarding the 30 minutes of Surgeon @ ATP played on John Peel's show...it's available on soulseek. I have it and can share it, message user name urban myth and I'll add you to my list. I've not given it a listen yet...but I was at ATP and it was definitely one of the best sets I've ever experienced.
