I learned this one from George Gibson:

The Old German War

Come all of you good people, wherever you may be.
I hope you'll pay attention, and listen unto me.
My name is nothing extra; the truth to you I'll tell.
I am a brave volunteer, and I'm sure I wish you well.

At the age of sixteen, I joined that army grand.
I left old east Kentucky, and I sailed to a far-off land.
Our captain he informed us, and I'm sure he thought it right,
"Before the morning comes boys, I'm sure we'll have to fight."

We saw them Germans coming. Lord, we heard them give their yell.
Our feelings at that moment, no human tongue can tell.
We saw their shining rifles, and their bullets around us flew.
Now all my strength had left me, and all my courage too.

I've been across that great ocean, I've road down streets of hell.
I've been in the midst of battle, I know its trials well.
I've lived a life of misery, and been where death it roamed.
I'll tell you from experience boys, you had better stay at home.
