He was the voice of Chef on the animated TV show South Park. On many episodes, he sang deep Soul ballads to seduce ladies like Kathie Lee Gifford. Hayes quit because of a Scientology episode that was done at the end of season 9. He was a recent convert to Scientology and this upset him. (thanks, Stefani - Amherst, WI)
Before he started recording, he was a successful songwriter. He wrote many of Sam & Dave's hits in the '60s, including "Soul Man" and "Hold On I'm Coming."
He played keyboards as a session musician for Stax Records, a legendary record label in Memphis.
His full name is Isaac Lee Hayes. He was born in Covington, Tennessee.
Isaac Hayes' main claim to immortality stems from his US #1 and UK #4 hit single "Theme From Shaft" in 1971. However, this was not his only hit. For example, "Disco Connection," as credited to the Isaac Hayes Movement, got as high as UK #10 in 1976. (thanks, Derek - Hull, England, for above 2)
Hayes was much better as a musician than as a business man. He declared bankruptcy in 1977 after the failure of his own label, Hot Buttered Soul Records.
He earned the nickname the "Black Moses Of Soul," and was the first famous black performer to wear chains as a symbol of success.
Hi parents died in a car accident when he was still an infant. He was raised by his grandparents in Covington, Tennessee. (thanks, Bertrand - Paris, France, for above 3)
As told to Terry Gross on National Public Radio, before he hit puberty, Hayes had a high, squeaky voice. He went through a dramatic voice change and ended up "Down in the basement."
