I'd be interested in knowing which version was done chronologically...I know that Ashford and Simpson wrote and produced the Dynamic Superiors, so I just assumed that it was written FOR them, and the other artists like Ace Spectrum, Millie Jackson, etc covered this version. Does anyone know? I love this song with the Ace Spectrum version being one of my favorites versions of any song. I love this group too particularly Shoe Shoe Shine and Leave It Alone. Stone Cold Jams!
