Sly Stone: You Can Leave Your Hat On

From rollingstone.com:

The last time the world saw Sly Stone was at his 1993 Rock & Roll Hall of Fame induction. His appearance at the ceremony was a surprise, his speech brief: "See you soon," was all he said. More than a decade has passed since his remark.
On Monday night, however, there was a rare sighting of Sly Stone at Hollywood's Knitting Factory. Stone's little sister Vet was performing with a Sly and the Family Stone tribute band, the Phunk Phamily Affair, in a show to benefit the Los Angeles Braille Institute.

Pulling up in front of the club on a four-wheel Harley, Sly was whisked upstairs to the VIP room where, ironically, he went unnoticed by the roomful of mostly blind musicians who were guests of the club that night. Keeping his motorcycle helmet on throughout, Sly smiled widely as he watched the ten-piece perform a scorching ninety-minute set featuring Stone hits "Dance to the Music" and "Hot Fun in the Summertime."
