The Credibility Gap was a satirical comedy team comprising Harry Shearer, Richard Beebe, David L. Lander and Michael McKean.[1] Lew Irwin, John Gilliland, Thom Beck, and Len Chandler also performed in their early days. They emerged in the late 1960s doing comedic commentary on the news for the Los Angeles AM rock radio station KRLA 1110, and proceeded to develop more elaborate and ambitious satirical routines on the "underground" station KPPC-FM, Pasadena, California.
