It's always been assumed that if Scherrie and Susaye would have continued the Supremes after Mary's departure that Joyce Vincent would have rounded out the trio.

I've always heard rumblings that Alton McClain was a possible "replacement"; that said, if she had joined the Supremes, do you think that the group would gone in the direction that Destiny would later in 1978/1979?

Here's their hit "It Must Be Love", produced by Frank Wilson.

Alton seemed geared for solo career, as evidenced by the "Alton McClain and Destiny" name. Would Alton McClain and the Supremes have made sense? Would Scherrie and Susaye have gone for it? Would Mary have "allowed" it?

Interesting, Alton definitely has a"Supreme" vibe and really favors Mary in the looks department.
