Isaac Hayes Tribute. Pioneering singer, songwriter and musician Isaac Hayes has died in Memphis. He was 65.
Authorities say a family member found him unresponsive near a running treadmill at his home. He was pronounced dead an hour later at a hospital. The cause of death is not yet known.
Along with his mellow, deep, voice, Hayes is also remembered for his striking visual image -- sunglasses, shaven head and gold chains.
Hayes' 1971 Number-1 hit ``Theme From Shaft'' won Academy and Grammy awards.
But it was his 1969 album ``Hot Buttered Soul'' that first made him a star.
He sang in a ``cool'' style, he prefaced the songs with ``raps,'' and the numbers had lush arrangements that ran longer than three minutes.
Hayes became the voice of Chef on ``South Park'' in 1997. But he angrily left the show saying an episode mocked his religion
