I'm not 100% certain but this sounds like the mix I've been looking for forever - from the This Is... Techno compilation, 1996. Lost my copy years ago, but I was convinced I'd find it on an official release somewhere. Apparently not!
Cheers. I believe it's the full ambient mk 1 version. I can't find it as an official release. The ambient mk 1 edit is this version exactly but being an edit fades out when the drums cut in. I can't find a full dance mk 1 version, there is an edit so it must exist. I believe the ambient mk 1 version on the give peace a dance album to be dance mix 1.
