Some hot mess. No mentions of the wiki's - mom, biscuits, Ottawa &c &c in Rice's 1917 sheet music. The source was American Children's Folklore, Bronner, 1988. My browser just shows a blank page on the link. Fwiw:

“Written at the Battle of Ypres, 1915
“I WANT TO GO HOME”
Words and Music by
Lieut. GITZ RICE,
1st Canadian Contingent

When first I joined the Army, not so long ago,
I said, “I'd fight the foe, and help Sir Douglas Haig, you know.”
I've been in France just sixteen months, and fighting now as yet,
I haven't seen a German all I've seen is mud and wet.
Tomorrow, when the officer asks “What would you like to do?”
I'm going to stand right up and say, “If it's all the same to you,”

CHORUS
“I want to go home, I want to go home;
The Whiz-bangs and Sharpnel around me do roar,
I don't want this old war anymore;
Take me far o'er the sea,
Where the “Alleman” cannot get me,
Oh, my! I don't want do [sic] die,
I want to go 'ome.” –– 'ome.” –– .”
