Pete Seeger, at Powerline. Gotta admit that Pete did a good job with Abiyoyo and Sam the Sailor or the Whaler or whatever it is called. I heard him perform years ago at Tanglewood.
His dangerous innocence has made him good with kids' songs, and a fervent supporter of mass-murdering totalitarian oppressors of the common man - provided they were of the Commie variety. Thus his inscription on his banjo, Woody Guthrie-style, "This machine kills fascists," has an unintended irony which Jonah Goldberg would appreciate.
