It's tough to say. I do ponder things like that though, as well as if Flo stayed in the Supremes would Diana have stayed longer, what if Mary just accepted Syreeta as Diana's replacement, yadda yadda.....Overall I think Jean would have stayed if they took a break from touring before switching to a different label. From what I understand without having a hit record that wasn't really an option for the group. It seems like touring wasn't really Jean's thing, she was missing several shows during 1972. Also her and Mary clashed over many things so it's hard to say would they have kept their differences aside being at a different record label.
