Frank, quite seriously, your theory makes much sense and would tie in quite well with the actual "flavor" of the song and the context.

On a less serious note.......Like I said, the impact would have been less if it went:

When you go to west P A,
Where they cook with lots of fat,
The earth is Fritz, the fire is Horst,
and they call the wind
Kretchblatt.

Doesn't work for me.........
