Legendary folk singer, banjo player, storyteller, and political and environmental activist Pete Seeger turned ninety on Sunday. More than 18,000 people packed New York’s Madison Square Garden Sunday celebrate the man, the music and the movement. The all-star lineup included Bruce Springsteen, Joan Baez, Rage Against the Machine’s Tom Morello, Ani DiFranco, Bernice Johnson Reagon, Billy Bragg, Ruby Dee, Steve Earle, Arlo Guthrie, Guy Davis, Dar Williams, Michael Franti, Bela Fleck, Tim Robbins, Dave Matthews, Rufus Wainwright, John Mellencamp, Ben Harper, and Ritchie Havens. We speak with some of the musicians, play Seeger’s music and play excerpts from our hour-long interview with Seeger in 2004. http://www.democracynow.org/2009/5/4/legendary_folk_singer_activist_pete_seeger
