Thatīs a very interesting thread. IMHO a Brenda Holloway has not the charisma of Mary Wells, she was a star. Itīs an intersting question, if she stayed, she would have been a great Motown Superstar ? When we compare it to all the other Motown Artist, they were in the shadow of The Supremes, Marvin Gaye too. Maybe when Mary remained at Motown, so Smokey worked with her, not with the Marvelettes. So "Donīt mess with Bill" or "The hunter" would be perfect songs for her on the other hand, when we see, that she did HDH songs "WYLMB", "YLTWB", "HB" or "OBFH", then itīs the question, if The Supremes had a chance to become Superstars ? How it would be sounds, Mary Wells sings "Where did our love go"? IMHO her voice was made for Smokey songs !
