Johnny Staccato, played by John Cassavetes, is a jazz pianist/private detective. The setting for many episodes is aGreenwich Village jazz club belonging to his friend, Waldo, played by Eduardo Ciannelli. The show featured many musicians, such as Barney Kessel, Shelly Manne, Red Mitchell, Red Norvo, and Johnny Williams. (Ironically, given the show’s New York setting, all of these men were closely identified with the West Coast jazz scene, as the show was filmed largely in Los Angeles.) Elmer Bernsteincomposed both of the main theme tunes used and Stanley Wilson was music supervisor. Cassavetes also directed five episodes.
