Pearl Jam frontman Eddie Vedder, Jackson Browne and Sean Penn are to star in a new documentary that highlights celebrity activism.
Vedder and Penn performed as part of a song and spoken word concert in Malibu, California on Thursday night (01May08), and their efforts were filmed for new movie The People Speak.
Vedder performed Phil Ochs' folk anthem Here's To The State of Mississippi, changing lyrics to take aim at President George W. Bush, while Browne sang Lives in The Balance.
The performers, which also included Chris and Rich Robinson of the Black Crowes, Taj Mahal and Don Cheadle, brought out the stars to the Malibu Performing Arts Center.
The celebrities in the audience included Diane Lane and Barbra Streisand - Lane is married to the event's host Josh Brolin, who is Streisand's stepson.
