I put my own case down to adverse reactions to the airwave bombardment 24/7 back in the day by The Osmonds, Bay City Rollers, David Cassidy, Mud, Slade, Sweet, Showadywaddy etc..
I have 'The Phantom' and the 'Say It Loud' and 'Eddie Gales Ghetto Music' on Water CD. All of them excellent - up to Mosaic-type production standard in fact. 'Black Rhythm Happening' I have on 'Four Men With Beards' vinyl (also good) and the 'Brown Sugar' on Blue Note original vinyl.
Apparently it is rare on CD. I've sold a number of these on vinyl, and the winning bids were all in the 75-125 range.
Ah, that explains it. I think my vinyl cost a reasonable £50.
I've got original Audio Fidelity vinyl of these two. I'll dig them out over the next few days and check. Sound as I recall was OK without being outstanding.
