He was raised in the Far Rockaway section of Queens and inThe Bronx.

Directors viewed Kaye as a master of the Broadway idiom during the last phase of the musical comedy era. This was evidenced by his introduction of three of the greatest show-stopping numbers of the era: "Fugue for Tinhorns" and "Sit Down You're Rockin' the Boat" from Guys and Dolls (1950) and "Jubilation T. Cornpone" from Li'l Abner (1956). in 1953 he played in a remake of It Happened One Night, You Can't Run Away From It.

He also played Marryin' Sam in Li'l Abner, again on both stage and screen. In 1962, he played the Mikado in Michael Winner's The Cool Mikado.

In 1965, he played alongside Nat King Cole as a travelling musician in the western/comedy Cat Ballou, starring Jane Fonda and Lee Marvin.

In the 1959-1960 television season, Kaye co-starred with William Demarest, Jeanne Bal, and Murray Hamilton in the NBC 18-weeksitcom Love and Marriage. Demarest played William Harris, the owner of a failing music company who refuses to handle popular rock and roll music, which presumably might save the firm from bankruptcy.
