Walrus, Ewan MacColl sang the song on his ca1959 album "Bless 'em All." The tune he used was "Ten Thousand Miles Away."

His text is from the 1945 "Airman's Song Book." I suspect it has been bowdlerized a little.

Oscar Brand recorded a U.S. version not long after. It is debowdlerized but very likely his own rewrite. Brand's tune was a
Stephen Foster song, "The Glendy Burke," IIRC.
