I prefer the Scherrie led version of "Missing", but the duet version is great too. It's one of the gems IMO from that time of the group's existence. Mary does a nice job with it on her own but I miss Scherrie. Mary's ballads were among the highlights of the Supremes during the Scherrie years, even more so, I feel, than many of Scherrie's numbers. However, "Where Is It I Belong" is a horrible song. Maybe it isn't horrible, but instead just a song I hate. "I Don't Want to Lose You" is another one. Yikes. Other than that, Mary's ballads are great. Of her uptempo turns, "Early Morning Love" is a fantastic vocal from her. I'm always surprised that she keeps up so well with that track. But uptempo wasn't Mary's forte. "This Is Why I Believe" should've cost Mary her job. That may be the all time worst pairing of a Supreme and a song in the history of the group. She was not the right one.
