Fortunately, I found this nifty list of songs written, co-written, by Stevie for other artists. Occasionally (Whitney, Macca, and Jermaine, e.g.), Stevie also performs. These are listed, more or less, up to my favorite Stevie song first recorded by another artist; Stevie did subsequently cover a couple of these. LISTEN TO ALL.
First though, a couple cuts introduced to me by Chuck Miller recently:
1966 All I Do (Is Think About You) – Tammi Terrell (S.Wonder/C.Paul/ M.Broadnax)
1983 The Crown – Gary Byrd And The G.B. Experience (S.Wonder/G.Byrd) – also has a Stevie vocal.
