Although released after the Simply Red version, the Simply Red website notes that Mick Hucknall wrote "Shine" specifically for Ross:
This track is on the Men And Women album [[1987) and was written for Diana Ross who also recorded it for her Red Hot Rhythm & Blues album [[1987)

[[and Mick seems to sing the song from a women's perspective -- "boy", "pearls").
Back in 1987, I was hoping they would release "Shine" as a single, as I loved it, as I did "It's Hard for Me to Say."
