I wouldn't call you unsophisticated. That is some pretty heavyweight syncopation happening. No one is just going to up and grab hold of that without some serious effort. I see it kind of like his fingerprint. Definitely some class in session stuff for me too. I can't say 100% certain but I think all of that track is CL White. Pretty killer.
I can see how you'd also like the Johnnie Wilder jr version better. It's also great. This is why I asked because I have a hard time pulling myself away from either of those versions to jump to the other one. He was the lead singer of Heatwave and at the height of success he was hit by a dump truck and paralyzed from the neck down. He became a Christian so maybe it was for God's glory. Pretty impressive performance, it is all done by him, by a parapalegic. Here is a Heatwave classic. The keyboardist is Rob Templeton, who went on to write a bunch of Michael Jackson hits, among many others.
