Answer
Luther Vandross worked with Donny Hathaway as a backing vocalist in the late 1970s. Vandross was a member of Hathaway's backing band, and the two men often sang together on stage. They also collaborated on several songs, including "Love, Love, Love" and "The Closer I Get to You." Hathaway died in 1979, and Vandross continued to perform and record as a solo artist.
