McGuinn, Clark & Hillman were an American rock group consisting of Roger McGuinn, Gene Clark, and Chris Hillman, who were all former members of the band the Byrds. The group formed in 1977 and was partly modeled after Crosby, Stills, Nash & Young and, to a lesser extent, the Eagles. They were reasonably successful commercially in the United States, with their debut album reaching number 39 on the Billboard Top LPs & Tape chart and the single "Don't You Write Her Off" reaching number 33 on the Billboard Hot 100.
