Now, for Anderson's (mostly identical) song, The Kaiser. I find The Kaiser to be a lot less coherent than The Boys and Uncle Sam, but it does have one unique stanza.

Listen to the song here: https://www.youtube.com/watch?v=nhdFn3d0XnE

THE KAISER

Old Kaiser said to the soldiers, "Come on, boys, and go
If we conquer Europe, this world is ours, you know
I hear them boys of your Uncle Sam"

"We have conquered little Belgium and France will soon be ours
And all the rest will surrender with all other powers
I hear the boys of your Uncle Sam"

Old Kaiser said to the soldiers, "Let's go up to the front"
But the soldiers said to Kaiser, "You will have to bear the blunt
You done gone to far with your Uncle Sam"

Defy the combined allies, he holds em all a-hand
But the voction from Uncle Sammy, the soldiers could not stand
The Dixie boys and the Yankees too

Old Kaiser, he said to his soldiers, put a pad in between my knees
and call for my physician I believe I've got the heart disease
I hear them boys of your Uncle Sam
I hear them boys of your Uncle Sam

The penultimate stanza (how's that for a fancy phrase!) is definitely an uncertainty of mine.

I would also make the underlined change of the final stanza to my lyrics above as well. You know what they say about hindsight
