Peat Bog Soldiers choise of Theodore Bikel.
Something to Sing About - The Personal Choices of America's Folk sings Collected and Arranged by Milton Okun, p. 103-106.

"....Bikel speaks and sings in more languages than most of us could readily identify. He is expecially adept i the language and folklor of Eastern Europe and Israel, reflected his own itinerant youth from Vienna to the Middle East. If there is a better interpreter of Russian Gypsy music about than Theo, let him step forward with his balalaika. If there is a performer more steeped in the songs of the Eastern European Jewish ghettos, let him speak. And if there is a more articulated and forthright singer of the bold new fulk music of Israel than Theo, may my left hand wither, or some less frightening Biblical injuction....."

Bikel's added verse:

Then will the peat bog soldier
March no more with their spaded to the bog.
Then will the peat bog soldiers
March no more with their spades to the bog.
