Just a thought, how many Golden World Acetates have surfaced over the years.
Ric-Tics too, possibly under the Golden World Logo as an acetate..
I have only seen a small amount, Including the Tape on ebay last year.
Following the purchase, did Motown absorb the whole catalogue into their Vaults, Master Tapes, acetates etc?.
In a recent "Ric-Tic relics Album thread", it was suggested that many were dubbed from disc for the Album.
So I'm guessing that many of the Original Master Tapes were neglected at the time of purchase.
I wonder if there is a project somewhere, either on tape ot acetate that may have been lost, relating to the Fantastic Four track.
