The New York Times has Pete Seeger’s obituary here. Slate has a transcript of Seeger’s testimony in front of House Un-American Activities Committee. An apt bit quoted in the Slate article:
MR. SEEGER: I feel that in my whole life I have never done anything of any conspiratorial nature and I resent very much and very deeply the implication of being called before this Committee that in some way because my opinions may be different from yours, or yours, Mr. Willis, or yours, Mr. Scherer, that I am any less of an American than anybody else. I love my country very deeply, sir.
CHAIRMAN WALTER: Why don’t you make a little contribution toward preserving its institutions?
MR. SEEGER: I feel that my whole life is a contribution. That is why I would like to tell you about it.
CHAIRMAN WALTER: I don’t want to hear about it.
