I brought it up on YouTube, and found this version; Marlene Dietrich, singing in English. Seeger's version is beautiful, but almost soothing in its gentleness; I was moved by Dietrich's face and voice, tragic and angry by turns, as the song really demands.
Sometimes the lyrics are changed; "they" becomes "we". I think that's better; there's no passing the buck.
