As far as I know, there weren't a lot of 45 singles released by Motown that had part 1 and part 2 as flips. Was there a particular reason why, I wonder? As I look at the increasingly longer productions by Norman Whitefield, especially, I would think that more singles by the Temps would have had part 1 and part 2 on the same single as flips. Is there something obvious I am overlooking?
