D (con’t)
There was a fat old Dutchman
His name was Dunderbeck
He was very fond of sausages
And sauerkraut and 'fet'
He ran a fine old butcher store
The finest ever seen
And he ground up all his sausage meat
In a wonderful machine

CHORUS: Oh, Dunderbeck, oh, Dunderbeck
How could you be so mean
I'm sorry you invented
That wonderful machine
For all the cats and long-tail rats
Will never more be seen
They'll all be ground to sausage meat
In Dunderbeck's machine
(last verse as we learned it)
One day there was something the matter
The machine she wouldn't go
And Dunderbeck, he crawled inside
To see what made it so
His wife she came along just then
A walking in her sleep
She gave the crank a heckofa yank
And Dunderbeck was meat.

And another variant
From: Loey B K:
Imagine my surprise to find this on the web! The words our dad sang to us were a bit different, though- I'll go look at your others . . .

There was a mean old Dutchman by the name of Dunderbeck.
He was very fond of sausages and sauerkraut and speck.
He owned the biggest butcher shop the finest ever seen
and he got himself a patent on a sausage meat machine.

Oh Dunderbeck, oh Dunderbeck how could you be so mean?
You shouldn't have invented that wonderful machine.
For pussycats and water rats will never more be seen.
They'll all be made int' sausage meat in Dunderbeck's machine.

One day something the matter was the machine it would not go.
So Dunderbeck he crawled inside the reason for to know.
His wife she had a nightmare and walking in her sleep
She gave the crank an awful yank and Dunderbeck was meat.

From Marty: Alternate Dunderback lyrics  
 My dad called him Johnny Greback.  He had a second verse that my cub scouts love:

One day a boy came shopping
A-shopping in the store
He bought a pound of sausages and threw them on the floor
The boy, he started whistling
He whistled up a tune
And all the little sausages went dancing around the room

Take care,
Marty
