I GREW UP WITH SHAFT, and that means I listened to hours of work by singer and arranger Isaac Hayes. The man won Grammy awards and an Oscar for the theme from the 1971 action film "Shaft." The Shelby County Sheriff's office reported that relatives found Hayes, 65, unconscious in his home next to a still-running treadmill. I spent a weekend in Shelby County, passing the hospital where paramedics attempted to revive the singer. Isaac Hayes died shortly after 8 PM Irish time today. No foul play is suspected. The world has less funk with the great man's passing.
