I heard a theory a while back that the follow - up's to some of our faves , that ultimately didn't get released , were sometimes better songs than the released sides so the company [RCA / Motown etc ] had an even better record to follow up with if the first record was a hit , which they weren't of course .I think this is why many of the RCA collectable sides are rare on Black issue , as they were demo'd in quantity and if they didn't get the thumbs up from the radio DJ's or the listening public , then very few stock copies were produced .Best,Eddie
