The Credibility Gap was an American satirical comedy team active from 1968 through 1979. They emerged in the late 1960s delivering 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 in Pasadena, California. Founded as a loose collective centered on KRLA staff members Lew Irwin, John Gilliland, Thom Beck, Richard Beebe, and folk singer Len Chandler, the group is chiefly remembered today for its 1971–79 lineup, comprising Beebe, Harry Shearer, David L. Lander and Michael McKean. History Lew Irwin and The Credibility Gap The Credibility Gap grew out of a company formed by Lew Irwin and Cliff Vaughs. KRLA 1110 hired news director Irwin to form The Credibility Gap in 1968 with his radio colleagues John Gilliland, Thom Beck, Richard Beebe, and folk singer Len Chandler. They took their name from the Vietnam-era term "credibility gap" (a euphemism for political dishonesty), and broadcast their comedy along with the news on KRLA. They first aired on the date of the 1968 California Primary. In 1968 (billed as "Lew Irwin and The Credibility Gap") they released An Album Of Political Pornography for Blue Thumb, consisting of highlights from their radio sketches. Thom Beck left in late 1968, and was replaced by Harry Shearer. Lew Irwin left a few months later, replaced by David L. Lander in February, 1969. The Credibility Gap In 1969, The Credibility Gap performed on KRLA's Pop Chronicles music documentary. By this point, Gilliland and Chandler had left, to be replaced by Bob Goodwin. This left Beebe the only original member remaining, and as the professional radio newsmen left, the Credibility Gap came to be dominated by comedians. Goodwin stayed with the group for about a year, but by late 1970, the Credibility Gap consisted of Beebe, Shearer and Lander. KRLA dropped The Credibility Gap's show in 1970, but Shearer found work as a disc jockey on freeform station KPPC and The Credibility Gap continued their on-air performances there. In 1971, the trio released the album Woodschtick, consisting of two long pieces that were somewhat in the style of The Firesign Theatre. Also writing and performing on the album was Michael McKean, who would be promoted to full membership after the album's release. Guest performers Christopher Ross, Morgan Upton and Albert Brooks would also work with the group
