I found an old moleskin journal amidst a bunch of old WWII letters from my grandpa to my grandmother. There's no name in it, but I believe it comes from my grandfather's side of the family. It's full of poems and songs circa late 19th and early 20th century. Here are the two versions:

Today is Monday to-day is Monday
Monday bullets O you lucky devil
we wish them all on you

WAR
Monay-bullets
Tuesday-shrapnel
Wednesday-bayonets
Thursday-front line
