Most of the film offers various performers singing or reciting his songs. Among those appearing are jazz diva Betty Carter, the Brodsky String Quartet, Elvis Costello, Lou Reed, Nick Cave, PJ Harvey, and bassist Charlie Haden. Also seen are dance numbers, and a reading of "What Keeps Mankind Alive?" ~ Sandra Brennan, All Movie Guide
