Isolation other mix

Anybody knows where does this come from?

Think I had this on tape back in the 80s, so it's been doing the rounds for a while. IIRC, it was on a tape I had with other 'unknown' demos / outtakes (as opposed to known demos - Central Sound Studios, Genetic, Transmission session etc.). I think the other demos / outtakes were of Candidate, New Dawn Fades, She's Lost Control & 24 Hours.

I was always under the impression that at least some, if not all, of them were fan-made.

If you don't get any luck getting an answer here, you could try asking on the forums at http://lwtua.websitetoolbox.com. There's some knowledgeable fans on there. Not that there aren't here, of course. ;-)
