Duane L. Tatro, who composed for nearly two dozen TV series, including such long-running hits as “Dynasty,” “The Love Boat” and “Barnaby Jones,” died Sunday at his home in Bell Canyon, Calif. He was 93.
Tatro’s music accompanied the action on “The FBI,” “Mannix,” “Mission: Impossible,” “Hawaii Five-0,” “Cade’s County,” “Cannon,” “Most Wanted,” “Vega$” and “Matt Houston,” as well as the comedy of “M*A*S*H” and the romantic melodrama of “Glitter,” “The Colbys” and “Hotel.” His first series was the sci-fi thriller “The Invaders” in 1967, and he worked steadily in TV for the next two decades.
He got to compose the series theme for just one show: Quinn Martin’s period detective drama “The Manhunter,” which lasted a single season in 1974-75.
