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]
