Is this the same ones that appear on Time Trip Vol. 4?
I believe there is so much satanic stuff due to the Olympic Studios refurbishment when they dumped loads of tapes etc in to skips during the 80's. I recall reading that there was supposed to be a beggars banquet sessions box set like the satanic one coming out(1997?), the jigsaw puzzle disc being a taster, but alas, nothing!?
