Cute!

But, really, the cannon is pretty astonishing in the first place in the 1812--a machine gun obligato would be nerve-wracking.

In checking the spelling of cannon here in MW, I read
that one of its definitions is that of the projecting piece from a bell:

can·on : the projecting part of a bell by which it is hung : EAR


Cool, huh?

Special note to Fiberbabe, if she should read here:

The word from which "ear" comes is an Old English word meaning "edge."
