Have you got your copy at hand? If I remember correctly they were all numbered individually and stating the total number of copies pressed? And yes it was 25, that's what I paid for the first copy, got a good deal from Chris when I ordered a few more copies for my mates.
Ken, you're right. Sound quality not the best. It varied from track to track, so were ok, some really bad. As they apparently were taken off a C90 tape it doesn't surprise me
But what still puzzles me, why did they include Eddie Holland - Outside looking in? The only track previously issued. Was it so in demand back then?
