Frederick "Dennis" Greene was born January 11, 1949, in New York, New York. He was raised in Harlem and the Bronx. 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.
