Panther (1983), Little provided the overdub as an imitation of Niven's voice. He performed similar duties to dub an imitation of James Cagney's stroke-impaired voice in the 1984 TV movie Terrible Joe Moran and in the 1991 TV special Christmas at the Movies by providing an uncredited dub for actor/dancer Gene Kelly, who had lost his voice. He also lent his voice to the narration of three specials that were the forerunners for the animated series The Raccoons: The Christmas Raccoons, The Raccoons on Ice, and The Raccoons and the Lost Star. In 1987, during the We the People 200: The Constitutional Gala television special, Little personified various historical figures, including Franklin D. Roosevelt, Edward R. Murrow, John F. Kennedy, Martin Luther King Jr., and Robert F. Kennedy. Little's performance was described as eclectic, impersonating Henry Fonda as Abraham Lincoln and doing Winston Churchill giving a rousing speech. The Tonight Show Little was a frequent guest on variety and talk shows in the 1960s and 1970s, and had an unofficial monthly slot on The Tonight Show Starring Johnny Carson for several years, and also guest hosted the program about a dozen times. He developed an impression of Johnny Carson, capturing The Tonight Show host's voice and many onstage mannerisms, and later played Carson in the HBO TV movie The Late Shift. Little's spot-on impersonation allegedly got under the thin skin of Carson, and he was permanently banned from appearing on the Tonight Show without notice or reason after his August 1982 appearance. Little claims in his biography that he was banned because Carson was offended by his impression, and this claim was supported by Henry Bushkin, Carson's long-time lawyer, who stated that nobody got under Carson's skin more than Little. Little had been doing the impression since the early 1970s, though, a decade prior to his bookings on the show coming to an end, including performing the impression to the Tonight Show''' host's face when Carson was the guest of honor at The Dean Martin Celebrity Roast of Johnny Carson in 1973. In response to Little's claims, Fred DeCordova, Carson's producer, said they just were not interested in hiring him any more due to his lack of new impressions. Las Vegas and later career Little has been appearing in Las Vegas since the mid-1960s, when he had dates at the Golden Nugget and went on to play at other Vegas
