Very interesting thread!

I’ve also always sworn I could hear Flo on “Santa Clause is Coming to Town,” even with the knowledge that they did not provide background vocals.

That being said, I’m not convinced Flo is singing on “I Hear a Symphony” [[the song). Especially after listening to the alternate extended mix on the IHAS Expanded album, it sounds like Mary and possibly Marlene.

What I find interesting is, in my view, I think Motown took a little more effort in the early years to make the Andantes’ presence on Supremes records a little more subtle. Meaning that they were added to add body to the sound, but Mary and Flo were still driving the background. Then once the Supremes started going out on the road more and more focus was put on Diana, it seemed less of a priority to preserve the original DMF blend.
