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", and broadcast their comedy along with the news on KRLA. They first aired on the date of the 1968 California Primary. In 1968 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. Goodman 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 albumWoodschtick, 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 during this era. Mark Deming writes of this transition:
n late 1968, Thom Beck left the group, and Lew Irwin followed in early 1969.... Joining the Credibility Gap in their absence were Harry Shearer... and David L. Lander.... By 1970, Len Chandler and John Gilliland had drifted away from the Credibility Gap, and... Michael McKean, had joined the team, though the troupe's relationship with KRLA had soured and their show had been shrunk from 15 minutes to a mere 180 seconds. However, after Shearer landed a side gig as a disc jockey on an FM "free form" outlet, KPPC, the Credibility Gap found a new home on the station, and the group's satire gained both sharpness and depth.
KPPC-FM fired all of its airstaff, including the members of The Credibility Gap, as part of a mass format change in 1971. No longer radio regulars, the group started performing in various clubs and concert venues. They also returned to the studio in 1972 to record a promo-only single for Warner Brothers, a four-and-a-half minute mini mock-rock opera called "Something For Mary". The Credibility Gap followed up this recording with the 1974 album A Great Gift Idea, which mixed satirical sketches with musical parodies. McKean and Shearer played guitar and keyboards, respectively, on the album, augmented by members of the bandLittle Feat. Beebe left the Gap in 1975. The Credibility Gap continued as an entity through 1979, but after 1976 individual members tended to focus on other projects and the group itself made only sporadic, widely spaced appearances. Beebe remained in radio news; McKean and Lander landed roles on the television series Laverne & Shirley that lasted from 1976 through 1983; and Shearer worked as a consultant for the TV series Fernwood 2-Night, as well as co-writing comedy albums and the 1979 feature film Real Life with Albert Brooks. The Credibility Gap issued a single in 1977, and continued their New Year's Day Rose Parade broadcasts annually through January 1, 1979; highlights of these broadcasts were collected on the 1979 album Floats. As well, selections from their earlier radio material were compiled on 1977's The Bronze Age of Radio. Shearer became a writer/performer on Saturday Night Live in September, 1979. This necessitated Shearer's move to New York and essentially brought The Credibility Gap's activities to a close.
After The Credibility Gap
The group disbanded in 1979, but the members have had occasion to work together since—notably the pairings of McKean and Lander as Lenny and Squiggy on the situation comedyLaverne & Shirley and Shearer and McKean as members of the mock-rock band Spinal Tap. Three of the surviving members held a reunion at the Museum of Television and Radio in 1999.
