From August 18th, 1969- February 11th, 1972 Merv Griffin appeared in a late-night talk show format on CBS-TV. It's believed that all of his CBS talk shows were bulk-erased by the network. In 1972, Griffin returned to the syndication market where he remained until 1986.

On this program, Merv's guests are Sammy Davis Jr. and Desi Arnaz Jr. The program is interrupted by a CBS news bulletin regarding the latest in a series of plane hijackings.
