In 1967, after trying his hand at a syndicated talk show several years earlier, Allen briefly returned on CBS with most of his old regulars for "The Steve Allen Comedy Hour", an eight-week summer replacement series on Wednesdays at 10:00pm Eastern (replacing the cancelled "Danny Kaye Show"). 21 minutes of the premiere episode featured one of Allen's favorite sketches, "The Prickly Heat Telethon", which Allen ran on film in its entirety at his 1973 Carnegie Hall concert. The short-lived series featured the debuts of Rob Reiner, Richard Dreyfuss, and John Byner, and featured Ruth Buzzi, who would become famous soon after as a regular on "Rowan & Martin's Laugh-In".
