There was a friend of ours a s a teenager who used to work for a record comapany and have "white label" promotional copies that we used to tape...
So we had a lot of these before release
I nust admit to s ome fond memories as a teenager of parties sat with a young lady on a sofa enjoying these albums (amongst other things)
Not going off topic, from the same source that we found "Tangerine Dream", and developed into Kraftwerk as well
My mate loved them..and the ozric tenticles, i liked them also but he was a fan
