Otis ‘Damon’ Harris, a soul singer who sang with Motown legends The Temptations, has died, according to a report in the Baltimore Sun. He was 62 years old.

Harris was only 21 years old when he first joined The Temptations in 1971, replacing Eddie Kendricks. At the time, he was a full decade younger than the rest of the members of the group. Harris was forced to take a new stage name because the group already had an Otis: bandleader Otis Williams.

While with The Temptations, Harris sang on a number of their biggest hits, including “Superstar (Remember How You Got Where You Are)” and “Papa Was A Rolling Stone,” which won multiple Grammys in 1972. Harris left the group in 1975 and his old group, The Young Vandals, for a few singles before embarking on a solo career.

After he was diagnosed with prostate cancer, Harris devoted himself to raising awareness for the disease and raising money to find a cure.  He founded The Damon Harris Cancer Foundation in 2001 to advance this cause, specifically to raise awareness of the risk for the disease for African-American men. He passed away in hospice care in his hometown of Baltimore over the weekend.
