Freedom! Richie Havens at Pete Seeger's 90th Birthday Party. I went to Pete Seeger's birthday party! Granted it was at Madison Square Gardens, but I still feel pretty special. Also on the bill was Pete Seeger (of course), Bruce Springsteen, John Mellencamp, Arlo Guthrie, Joan Baez, Kris Kristofferson, Roger McGuinn, Ani DiFranco, Taj Mahal, Ben Harper, and Dave Matthews. Have to say though that Richie Havens stole the show.
