Which 1960s vocal group had Eddie Kendricks and David Ruffin among its lead singers?

The 1960s vocal group that included Eddie Kendricks and David Ruffin among its lead singers was the Temptations.

Formed in Detroit in 1961, the Temptations became one of Motown’s defining vocal groups. The classic lineup included Otis Williams, Melvin Franklin, Paul Williams, Eddie Kendricks, and David Ruffin, who replaced Elbridge “Al” Bryant in 1964.

Kendricks was known for his distinctive tenor and falsetto leads, including “The Way You Do the Things You Do” and “Get Ready.” Ruffin became the lead voice on several of the group’s most celebrated recordings, including “My Girl,” “Ain’t Too Proud to Beg,” and “I Wish It Would Rain.” Their choreography, coordinated fashion, and layered harmonies helped establish the modern soul-group template.

The Impressions, the Miracles, and the Four Tops were also major vocal groups, but none matches the specific combination of Kendricks and Ruffin in this question. Ruffin left in 1968, while Kendricks departed in 1971; the Temptations continued with changing lineups.
