Grew up middle class, went to prep school and Harvard, affected a working class style but I doubt any working class people were ever interested in him. A likeable old commie, naive and innocent to the end.Ron Radosh at PJMedia who knew Seeger personally concluded with this:
I know Pete would not have said that if I had been writing books about fascism.
More than likely, he would have praised my doing so. Pete, like so many others on the Left, simply failed to realize that communism is fascism’s twin.
Some also take umbrage, as does Graham, with calling Seeger anti-American. In his Mother Jones  article, David Hajdu, who spent time with Seeger before writing the article, called him “devoted to a few simple ideas, a nostalgist whose worldview often seems frozen in the era of his own coming-of-age.” He adds: “A strain of anti-Americanism has always run through Seeger’s work.”
If you don’t think that is the case, listen to the Smithsonian Folkways CD “Pete Seeger Sing-a-Long,” recorded at the Sanders Theater in Cambridge, Mass., in 1980. In an impromptu remark, Seeger makes a comment about how if the people had guns, you better watch out, because you don’t know whom the people would use the guns against. The comment receives huge cheers. That is to be expected of from an audience in the People’s Republic of Cambridge.
Sunkara is right about one thing. He quotes Bruce Springsteen, who wrote that Seeger showed how song could “nudge history along.” Seeger did indeed help make communism more fashionable, and that is a tragedy, not something for which Pete Seeger should ever have received praise.

Related: Spengler: Pete Seeger: A Mean-Spirited and Vengeful Recollection. “I was not just a Pete Seeger fan, but a to-the-hammer-born, born-and-bred cradle fan of Pete Seeger. With those credentials, permit me to take note of his passing with the observation that he was a fraud, a phony, a poseur, an imposter. The notion of folk music he espoused was a put-on from beginning to end. There is no such thing as an American ‘folk.’”
