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.
