Just saw this from a CNN feed...

Soul singer and arranger Isaac Hayes, who won Grammy awards and an Oscar for the theme from the 1971 action film "Shaft," has died, sheriff's officials in Memphis, Tennessee, reported Sunday.

Relatives found Hayes, 65, unconscious in his home next to a still-running treadmill, said Steve Shular, a spokesman for the Shelby County Sheriff's Department.

Paramedics attempted to revive him and took him to a hospital, where he was pronounced dead shortly after 2 p.m., the sheriff's department said.

No foul play is suspected, the agency said in a written statement.

Hayes was born in Covington, Tennessee, the second-born child of Isaac Sr. and Eula Hayes, but after their deaths was raised by his grandparents, Mr. and Mrs. Willie Wade, Sr. The child of a poor family, he grew up picking cotton in Covington. He dropped out of high school, only to be encouraged later by his former high school teachers at Manassas High to get his diploma, which he earned at the age of 21. He began singing at the age of five at his local church, and, soon after, he taught himself to play the piano, electronic organ, flute and saxophone.

For me, Issac Hayes is best known for being the voice of "Chef" on South Park.

He will be greatly missed.
