Columbus Day was last Monday. We had classes anyway so I forgot (though not getting mail was a clue). There have been a few good songs about Christopher Columbus, including the classic Tin Pan Alley-era tune with lyrics by Andy Razaf and music by Leon Berry (though sometimes credited to Andy Kirk) that was popularized by Duke Ellington.

Mister Christopher Columbus
Sailed the sea without a compass
When his men began a rumpus
Up spoke, Christopher Columbus

There is land somewhere
Until we get there,
We will not go wrong,
If we sing, "swing a song"

Since the world is round,
We'll be safe and sound
Til our goal is found,
We'll just keep rhythm bound

The full lyrics are here.
