Joel Vance, in his 1977 biography of Fats Waller, mentions in passing
that the black 24th and 25th Infantry in the Spanish-American War of
1898, trounced the Spanish at Las Guisamas in hand-to-hand combat,
singing "Hot Time in the Old Town".

Not quite the same today; singing doesn't quite go with pressing the
trigger on a flame-thrower.
