when motown introduced High Inergy, they created some angst with Pedro, Mary and the Supremes because one of the Gordy sisters was quoted with saying they could be even bigger than the Supremes, to which Pedro made a comment that it makes no sense to bring in a new group like this unless you plan on phasing out the old one

would Turnin' On and the material HI recorded in 77 have been strong material for the Sups?

if mary had accepted Motown's offer to manage the group, they could have certainly continued w the Hollands and done the MS&S album, IMO. but then in 77, where would they have gone? would motown have leveraged this HI content and help reinvigorate the Sups?
