Going by the tracks, those were done Stafford-era, still collectable titles, it's all part of the scene - sod ethics, a lot of people would love to be able to play these, in or out.
Tell you what, 3 years ago I was getting a lot of acetates cut for myself and I sold them in the end, there must have been 15 double siders with things like cheating kind, ray agee, that sort of stuff - I sold the lot to a someone who is considered a 'big name dj' and theres no doubt he played them out before tracking down the originals. You probably wouldn't believe me if I told you who it was.
