He was a member of his alma mater's all-male a cappella group, the Columbia Kingsmen. The group formed in 1969 at Columbia University in New York, and went on to become better known as Sha Na Na . The name change occurred because of another group with the same name, which was known for the song Louie Louie.
The television show Sha Na Na was on the air from 1978 to 1981. Greene choreographed the majority of the moves for the show, on which he was known simply as Denny. Denny was portrayed in the series as the most intelligent member of Sha Na Na. Greene sang lead in the song "Tears on My Pillow" when he appeared with Sha Na Na in the movie Grease, in 1978.
Greene received his high school diploma from the Hotchkiss School and a B.A degree from Columbia University in 1971. After he left Sha Na Na, he went to law school, which he had been interested in doing since childhood. He studied several areas of law, including constitutional law, entertainment law, and race and American law. He earned an M.A. degree from Harvard University in 1984 and a J.D. from Yale University in 1987.
