Clyde Martin, a veteran stage actor and opera host, died Monday. He was 78. The longtime Oklahoma City resident studied acting at the Pasadena Playhouse and appeared in scores of comedies, dramas and musical theater productions at Lyric Theatre, the Jewel Box Theatre, Carpenter Square Theatre and others. In 1966, Martin began hosting an opera show on KJEM radio. His show ran until the station was sold in 1969. Not long afterward, Martin began what would become a 35-year stint as host of the Metropolitan Opera and Chicago Lyric Opera radio broadcasts at KCSC-FM. Martin also was host of his own opera show, "Clyde Martin's Opera,” which featured noted recordings of some of the world's most prominent opera singers. His passion for music, combined with an encyclopedic knowledge of opera, earned him the affectionate title "Mr. Opera.” Martin worked for many years for the Metropolitan Library System and retired from there in 1994. Services are pending.
