So I imagine that virtually every record by a band that the Wrecking Crew performed on was a fraud too???... It was generally the Wrecking Crew who were the studio musicians on recordings by Beach Boys, The Association, The Grass Roots, The Byrds, Herb Alpert & The Tijuana Brass, Gary Lewis & The Playboys most of whom freely admitted that they could not do the job in the studio that the instrumental "masters" could...and so any more. It's the difference in presentation of recordings and the touring acts... Obviously, the Andantes, while most would say were vocally tighter as a vocal ensemble to the Supremes backup capabilities [[as good as they were and capable to do live performances), but couldn't come close as to their stage look, stage moves, etc... Go with the best you've got. The unfortunate part is that the Andantes weren't compensated for the recordings as the other Supremes were...
