Bingo, I can't wait until our crack team over in the Anthology thread decipher all the clues. It will be fun to follow along (without dropping the 3 hundo).
They have to start with Mary Wells seeing as she's a prolific Motown song writer and the first lady of Motown. They might do her self titled, but her My Guy is the record with the most success.
Did you check out the clues? cuz that seems pretty spot on guess. I am not super knowledgeable on Motown, beyond Stevie, Marvin, and the Jackson 5. It's not that I dislike it, I have enjoyed about everything I've heard just never done a deep dive.
