The Freedom Singers and Pete Seeger (1919 - 2014) at the Newport Folk Festival (©1963) Pete Seeger's singing embraced and promoted progressive causes over seven decades -- the labor movement, civil rights, peace, and the environment. He inspired many other folk singers and activists. Seeger encouraged audiences to sing along with him and once said, “the key to the future of the world is finding the optimistic stories and letting them be known.” (More photos in the People Gallery...)
