SONG THAT WON'T LEAVE MY HEAD: Why all of Pirates of Penzance, of course, which I have been listening to and watching at saturation levels recently (it's the movie version.)

When the foeman bares his steel,
Tarantara! tarantara!
We uncomfortable feel,
Tarantara!
And we find the wisest thing,
Tarantara! tarantara!
Is to slap our chests and sing,
Tarantara!
For when threatened with ‚meutes,
Tarantara! tarantara!
And your heart is in your boots,
Tarantara!
There is nothing brings it round
Like the trumpet's martial sound,
Like the trumpet's martial sound

And I love this part which stands as the movie's only serious moment:

KING: Although our dark career
Sometimes involves the crime of stealing,
We rather think that we're
Not altogether void of feeling.
Although we live by strife,
We're always sorry to begin it,
For what, we ask, is life
Without a touch of Poetry in it?
(all kneel)

ALL: Hail, Poetry, thou heav'n-born maid!
Thou gildest e'en the pirate's trade.
Hail, flowing fount of sentiment!
All hail, all hail, divine emollient!
(all rise)

In times like these we could all use a little 19th-century pop culture. Penzance is also interesting in that it debuted in New York City and London at the same time in an attempt to get a copyright on it and to prevent bootleg performances like there had been with H.M.S. Pinafore.
