Thanks for the kudos, Wolfgang, but dearie me no I didn't translate it. All the info I have is at the bottom the post. The "Heritage Collection" was printed in 1976 for the US Bicentiennial in 1976 and this particular edition is out of print. HOWEVER, Joe Offer says it is re printed and still available as Jerry Silvermans Folk Song Encyclopedia, or something like that. No translator credit was given, just says "from the Spanish Civil War, German song"
