When a young Richard Marx moved from Chicago to Los Angeles and was amassing rejection letters for his demos, Lionel Richie gave him a shot, and had him sing backup on this track. Before he hit it big as a solo artist, Marx lent his vocals to several other Richie recordings, including All Night Long.
