After South Park[edit]

Hayes' income was sharply reduced as a result of leaving South Park.^[46] There followed announcements that he would be touring and performing. A reporter present at a January 2007 show in New York City, who had known Hayes fairly well, reported that "Isaac was plunked down at a keyboard, where he pretended to front his band. He spoke-sang, and his words were halting. He was not the Isaac Hayes of the past."^[46]

In April 2008, while a guest on The Adam Carolla Show, Hayes stumbled in his responses to questions – possibly as a result of health issues. A caller questioned whether Hayes was under the influence of a substance, and Carolla and co-host Teresa Strasser asked Hayes if he had ever used marijuana. After some confusion on what was being asked, Hayes replied that he had only ever tried it once. During the interview the radio hosts made light of Hayes's awkward answers, and replayed Hayes comments as sound drops – often simulating conversation with his co-hosts. Hayes stated during this interview that he was no longer on good terms with Trey Parker and Matt Stone.^[47]

During the spring of 2008, Hayes shot scenes for a comedy about soul musicians inspired by the history of Stax Records entitled Soul Men, in which he appears as himself in a supporting role. His voice can be heard in the film in a voice-over role as Samuel L. Jackson, Bernie Mac (who died the day before Hayes), and Sharon Leal's characters are traveling through Memphis, Tennessee. His first actual appearance in the film is when he is shown in the audience clapping his hands as The Real Deal does a rendition of Hayes's 1971 hit song "Do Your Thing." His next appearance consists of him entering The Real Deal's dressing room to wish them luck on their performance and shaking hands with Louis Hinds (played by Jackson) and Floyd Henderson (played by Mac). During this scene, Hayes also helps Hinds reunite with his long-lost daughter Cleo (played by Leal). His final appearance in the film consists of him introducing The Real Deal to the audience.^[46] The film was released on November 7, 2008.

Two months after his death, the South Park episode "The China Probrem" was dedicated to him^{[citation needed]}.
