A close relative, sung by soldiers in WW1 can be found in S Louis Giraud's book 'Songs that won the war'
Mary had a little lamb, its fleece was white as snow
Shouting out the battle cry of freedom
And everywhere that Mary went, that lamb was sure to go
Shouting out the battle cry of freedom
Hurrah for Mary, Hurrah for the lamb,
Hurrah for the teacher, who didn't care a little bit
And everywhere that Mary went, that lamb was sure to go
Shouting out the battle cry of freedom
(Spoken) Baa-aa-aa-aa-aa!
Martin
