On further reflection, and after consulting with my father (who can't remember what he did this morning but can remember songs he sang 80 years ago) I have a couple of small corrections to make in the version I posted the other day.
In the first verse, the last line "And he invented and patented..." should be "And he took it out and patented...." (This really fits the rhythm of the tune much better.)
And in the chorus, the last line " 'Cause they'll all be..." should be "For they'll all be...."
These changes don't add any sense or meaning, but they are, in fact, the words we sang.
For the record then, my corrected version of Dunderbeck and the Sausage Meat Machine.
There was a big fat German, his name was Dunderbeck, And he was very fond of sauerkraut and speck. He opened up a butcher shop, the worst you've ever seen, And he took it out and patented the sausage meat machine.
[chorus] Oh, Dunderbeck, oh, Dunderbeck, how could you be so mean! Why'd you invent the sausage meat machine? The rats and dogs and pussy cats will never more be seen For they'll all be ground to sausage meat in the sausage meat machine.
One day a little boy came walking in the store To buy a pound of sausage meat and eggs a half a score. And while he was a waiting he whistled up a tune, And the sausage meat began to hop and dance around the room.
[chorus]
Something was the matter, the machine it didn't work. So Dunderbeck climbed into it to try and have a look. His wife was having a nightmare, and walking in her sleep She gave the crank a heck of a yank and Dunderbeck was meat.
