The Allen "Westinghouse Show" is considered a classic of American late-night talk shows today, given its professed influence on a number of comedy greats including David Letterman, Robin Williams, Steve Martin, Harry Shearer and others impressed by its wild, anarchic style, complete with outdoor stunts staged near the Hollywood Ranch Market, not far from the studio. The show's guests included such Southern California eccentrics as health food enthusiast Gypsy Boots, popular TV physics professor Julius Sumner Miller, Miles Davis and his group (1964), Lenny Bruce, Peter Sellers, Jackie Vernon (in his first television appearance), and a young Frank Zappa, who appeared as a "musical bicyclist."
