There are at least 3 Motown productions where it sounds like Motown may have been using another drummer on occasion other than Benny, Pistol and Uriel.

On Kim Weston's "You Hit Me [[Where It Hurt Me)", Brenda Holloway's "You're Walking Out With My Heart" and Stevie Wonder's version of "My World Is Empty Without You", the drums seem to have a very unique feel when it comes to the fills. It doesn't sound like Benny's style or Uriel's or Pistol's. I've heard how each of those drummers play a shuffle/swing beat and this style just seems altogether different. The fills are almost the aural equivalent of someone skating over the ice- hard to describe but there is a very seamless transition on the fills between the snare and tom-toms that is very different from Benny's style. Also, the fills tend to pop up almost anywhere and any time.

I'll post the songs, and maybe someone can tell me if this is one of the Big 3 or another drummer.
