Ndugu Leon Chancler with George Duke

Here's a cool video of Ndugu Leon Chancler in the studio with George Duke, playing Dukey Stick, which ended up on his record Don't Let Go. They start playing after about 1:45. The way Ndugu counts it in is hilarious: 

That's Napoleon Murphy Brock, best known from Zappa's band, doing background vocals here, and Sheila E. (Escovedo at the time) on percussion. The guitarist (“Goin' surfin baby!”) is Charles Johnson who much later became a well known blogger, writing the Little Green Footballs blog— which was very pro Iraq war during the Bush years, and has since become much more politically liberal.
