When I compare these two groups, IMHO they have the same sound, both were produced by HDH, later Frank Wilson, isn't it? I'm wondering about that fact, because the "male opposite" were The Temptations, but not in the sound. And then another question, why try Motown to develop a solo singer of The Four Tops, maybe Levi Stubbs as the male opposite to Diana Ross ?
Thanks for any reponse
