Hi Burl
My Brudda Sylvest is 1908, the Old Sow no doubt stems from the Albert Richardson 1920s recording, but is your version of 'A Soldier' recorded anywhere? How far back can you trace it in your family? I have seen no British versions that can be dated to earlier than the interwar period. My theory is that it evolved from American versions and was brought over by American troops in WWI.

Any chance you could post at least the words for us here please?

And while you're on why not post your version of C&M? It would also be helpful to give a few background details for future researchers.
