The version I heard as a Protestant, in a mostly Catholic neighborhood in Chicago, as a Boy Scout, in the mid-60's included the lines, "All who eat pastrami, join the Hebrew Army, fight, fight, fight for Palestine." We sang it, with some of the other verses as we hiked. Just like "A hundred bottles of beer on the wall." Learned from one of the troop leaders and never gave it much thought abot it. .Now I feel it is kind of Anti-Palastinian
