I can imagine the group voicing their opinion about the song, but there's no way any of them, Mary included, had veto power over what the label wanted to release. If Motown felt that strongly about it, it would have been the single. Just like if the label thought "He's My Man" didn't have a chance, it would never have been pressed and released as a single.

I wonder too if the fact that it was a cover of a Bobby Hutton song from a year or two before put them off, not wanting to start this next phase of Supremes off with something people may have heard before.

I'm not convinced the song would have done much better than "He's My Man", but it is a great song, single or not. I do think if I were in charge of singles and I had to choose between the two, I probably would have still gone with "He's My Man".
