Set The Controls for the Heart of the Sun (part 1). This is the final song from the KQED concert. Filmed in San Francisco on the 29th April 1970. This is the only known footage of them performing for television in the seventies. Shortly before the band released Atom Heart Mother, the band performed their current set for the cameras of public broadcasters KQED. The original master was thought to have been lost and the surviving footage has long been the preserve of bootleggers.
