After arriving in London, Hendrix sat in on a Cream show, and asked if he could jam with Eric Clapton and the band. This was an audacious request; Cream, the world's first rock and roll supergroup, were especially famous for their skill as live performers. Undaunted, Hendrix gets on stage and launches into Howlin' Wolf's "Killing Floor." He's a one man spectacle, playing with his teeth, behind his back, between his legs, all without breaking a sweat. .
