We sang two versions of this song when I was a kid, with elements of the above but slightly different. I always thought maybe the song originated with soldiers during WWI or WWII:

My country tis of thee
Sweet land of Germany
My name is Fritz
I love their sour kraut
It makes my ears sprout out
From every mountain top
Let sour kraut sprout

and:

My country tis of thee
Sweet land of Germany
My name is Fritz
The King is Donald Duck
He drives a garbage truck
His wife is Daffy Duck
She drives one too
