It's not often that someone in my "day job" suggests something that makes it onto this site. OK, I'm not sure it's ever happened, but there's always a first time.
I'm not sure that Perry Como is the first person to come to mind in terms of whose voice is best-suited for a novelty song -- it's Perry freakin' Como, after all, But this song, introduced to me by a co-worker and more than a half-century old, made me smile, and it might make your local 9-year-old geography-obsessed kid smile, too. (Why the changing languages and the martial step? Who. Knows.)
