Erik Kielholtz should like this one...

From Fiddleback Fever, Bowman the Black's Parody Songs of Roland, to the tune of "The Battle of New Orleans" and "Gaston."

He blew that horn and the Muslims kept a-commin’
There wasn’t quite as many as there was a while ago
He blew once more and they began a-runnin’
O’er Gibralter Rock and down to Morocco!

Must be seen to be believed.
