As you probably already heard, singer/actor Isaac Hayes died yesterday at his home in Memphis, TN at the age of 65 . The baritone singer/composer was probably most well known for creating the theme song for Shaft …that is, until he voiced the character Chef on South Park . He was killed off the show after Hayes became angry with an episode that made fun of his brother in Scientology, Tom Cruise. But before that nastiness, he had a great run of things and contributed lots of sexy songs, including this one, in which he explains the menstrual cycle to Stan.Issac Hayes Dies At Age 65 [Rolling Stone] Issac Hayes, 65, A Creator of '70s Soul Style, Dies [NY Times]
