Its a George Soule/Terry Woodford song and If you look at the rest of the Reuben Howell LP, its a Wishbone production, so 100% Muscle Shoals and IMO nothing really linking it to Motown apart from it being released on it. Womack had links down there from his time at American Studios, so I would have thought there was a good chance that the song was pitched to various artists at the same time. Given the production leaning of the RH LP and that he released it as a single, I'd have a leaning towards Reuben Howell being the primary, even if Facts of Life had an earlier release date.
