The Cisco Kid came to radio October 2, 1942, with Jackson Beck in the title role and Louis Sorin as Pancho. With Vicki Vola and Bryna Raeburn in supporting roles and Michael Rye announcing, this weekly series continued on Mutual until February 14, 1945. It was followed by a thrice weekly series on a Mutual-Don Lee regional network in 1946, starring Jack Mather and Harry Lang, who continued to head the cast in the syndicated radio series of more than 600 episodes from 1947 to 1956. The radio episodes ended with one or the other of them making a corny joke about the adventure they had just completed. They would laugh, saying, "'oh, Pancho!" "'oh, Cisco!", before galloping off, while laughing.
