According to the "Fireside Book of Folk Songs":

"It is generally believed that this song originated and was first sung in the Börgermoor concentration camp in 1933. Pierre Martinot, designer of this book, who was a prisoner in Dachau in 1944-45, says that the old prisoners there claimed that the song was first sung in Dachau, and that it was carried from there by underground to Börgermoor."
