I got this from a guy who used to go to conventions and posted lists under peoples chalet doors on the last day. This was back in the days of tape because a CD recorder cost £300, discs were about £3 each and you could only burn at 1x speed.
I bought a load of stuff from him on tape and this concert was included.
Never having seen or heard of it before (like many concerts which are now common place thanks to this website and the kind people who share them), I gave CD copies to all my friends around the world so it's probably my fault this has spread.
A few years later one of my friends told me it was fake.
I can't remember who that was now, but he certainly listened to every concert he had (which I never did and still don't) and realised he'd just listened to some of it under a different name.
I can't remember which concerts it "really" is (there's not many to choose from if anyone here wants to listen to all the early ones) but it's definately an edited mix of TWO of the better quality ones.
Is it made up of Golders Green & Rainbow (november) 74?
