Back in the 80s, a friend of mine had an LP of Vangelis' entitled To the Unknown Man, but I can't seem to find it listed. I seem to recall asking about this on here in the distant past. Was this LP a compilation?
That's a "Spiral" track. I'm not the most knowledgeable of Vangelis fans, but it's my understanding that it was used on a few Euro various artists comps in the 80's.
