When Pete Seeger turned 90 in 2009, the turnout of legendary musicians playing and singing with and for him at Madison Square Garden included Arlo Guthrie, Bruce Springsteen, John Mellencamp, Ani DiFranco, Billy Bragg, Kris Kristofferson, Emmylou Harris and even Oscar the Grouch from "Sesame Street." (Seeger and Oscar were old pals — Seeger appeared on the classic children's show as early as 1970, and recorded an album with "Sesame Street" characters in 1974.)
That's just a small testament to the influence of Seeger, who died Tuesday at age 94. His songs and his activism, his love of people and fight for peace, his belief that music could bring everyone together, weave through our history and will live on for many years to come.
Famous faces across the nation stopped to remember Seeger publicly as news of his death spread.
