Isaac Hayes, that pimpin’ progenitor of symphonic soul, died yesterday at 65; relatives found him by a still-running treadmill in his home in Memphis.

Hayes, aka Black Moses, contributed to the soundtrack of my high school years.

The lyrics include the iconic line, “They say this cat Shaft is a bad muthah” [then the girl vocalists drown him out] “Shut your mouth!”

Here’s a fun clip of Hayes on stage performing “Shaft” with his mammoth ensemble. A ’fro-wearing, dashiki’ed Jesse Jackson introduces him.
