i don't think so The Supremes needed to go on without Ross, because the group had been from 1967 revamped to suit another purpose. Can you imagine us not getting to hear Up the Ladder to the Roof, Stoned Love and Floy Joy, Nathan Jones, and RiverDeep Mt High under the name the 1970's The Velvet Honey's or the Golden Nuggets I don't think so, and Mary would have never agreed to this change as she didn't agree to it three years later, when the hits had dried up.
