When a policeman approached, Tao Rodriguez-Seeger said at the time he feared his grandfather would be hassled.
"He reached out and shook my hand and said, 'Thank you, thank you, this is beautiful,'" Rodriguez-Seeger said. "That really did it for me. The cops recognized what we were about. They wanted to help our march. They actually wanted to protect our march because they saw something beautiful. It's very hard to be anti-something beautiful."
That was a message Seeger spread his entire life.
With The Weavers, a quartet organized in 1948, Seeger helped set the stage for a national folk revival. The group — Seeger, Lee Hays, Ronnie Gilbert and Fred Hellerman — churned out hit recordings of "Goodnight Irene," ''Tzena, Tzena" and "On Top of Old Smokey."
Seeger also was credited with popularizing "We Shall Overcome," which he printed in his publication "People's Song" in 1948. He later said his only contribution to the anthem of the civil rights movement was changing the second word from "will" to "shall," which he said "opens up the mouth better."
"Every kid who ever sat around a campfire singing an old song is indebted in some way to Pete Seeger," Arlo Guthrie once said.
His musical career was always braided tightly with his political activism, in which he advocated for causes ranging from civil rights to the cleanup of his beloved Hudson River. Seeger said he left the Communist Party around 1950 and later renounced it. But the association dogged him for years.
He was kept off commercial television for more than a decade after tangling with the House Un-American Activities Committee in 1955. Repeatedly pressed by the committee to reveal whether he had sung for Communists, Seeger responded sharply: "I love my country very dearly, and I greatly resent this implication that some of the places that I have sung and some of the people that I have known, and some of my opinions, whether they are religious or philosophical, or I might be a vegetarian, make me any less of an American."
