According to the Associated Press, 65-year-old singer-songwriter Isaac Hayes has passed away after being found unresponsive in his Memphis, TN home.

An indelible influence on the world of music, a pop culture icon besides for his work as Chef on "South Park" and in its full-length feature, Hayes will be most fondly remembered in the world of film for his award-winning theme to Shaft and his role as 'The Duke' in Escape from New York.

Hayes showed up in his fair share of other movies, apparently including a cameo as himself in the upcoming comedy Soul Men, starring Samuel L. Jackson and the late Bernie Mac -- this after making an appearance on "The Bernie Mac Show" in 2005 and an uncredited cameo in the 2000 version of Shaft, starring Jackson.
