Gleason, Rudy Vallee, Mike Douglas, George Burns, and Al Hirt followed over the next two years. Peppiatt and Aylesworth also helped bring Little on to other American shows for which they wrote, such as The Jimmy Dean Show, The Kopykats, and The Julie Andrews Hour and continued to write material for his act after he moved to the US permanently at the end of 1965. In Canada, Little starred in his own show The Rich Little Show, on CBC Radio in 1966. He also made his first appearances on The Dean Martin Show and The Jimmy Dean Show during the 1965–1966 season. In 1965, Little provided the voice for the Pink Panther in two cartoons, Sink Pink and Pink Ice; these two cartoons were made by DePatie-Freleng Enterprises to experiment with giving the Panther dialogue, contrary to him usually being mute. In 1966 and 1967, Little appeared in ABC-TV's Judy Carne sitcom Love on a Rooftop as the Willises' eccentric neighbour, Stan Parker. He appeared on That Girl in 1967 as a writer who impressed Marlo Thomas' character with his impersonations. He also made two memorable appearances as accident-prone Brother Paul Leonardi on The Flying Nun in 1968; it marked one of his few appearances as a character actor rather than an impressionist. In 1969, he appeared in an episode of Petticoat Junction as newly engaged fiancé to Billie Jo in "Billie Jo and the Big Big Star". Nixon Little was most notable for impressions of U.S. President Richard Nixon. During the 1970s, Little made many television appearances portraying Nixon, and once performed his impersonation in front of Nixon himself, who Little says did not realize he was imitating him at all and "wondered why I was talking to him in such a funny voice." In 1972, he portrayed Richard Nixon with the voice and mannerisms of Oliver Hardy in Another Nice Mess. Little later appeared as Nixon on the soap opera Santa Barbara, in a 1991 fantasy sequence regarding Gina's ideal sperm donor. In 2020, Little developed Trial on the Potomac: The Impeachment of Richard Nixon, a one-man show based on the 2015 book The Real Watergate Scandal: Collusion, Conspiracy, and the Plot That Brought Nixon Down by Geoff Shepard, alleging a conspiracy to remove Nixon from office. 1970s Little was also a semiregular on the Emmy-winning ABC-TV variety series The Julie Andrews Hour in 1972–73.
