I just couldn't resist. Better quality version here: http://soundcloud.com/theodrixx/polka-pie

I really love naval marches, and Pinkie's Parasprite Polka adapts so easily to a march style, because... well, that's what it is, really. Accordingly, I had a drum line, a flute melody, and some piccolo to garnish. Brass keeps the rhythm and establishes the chord progression.

It's very simple, it took about one hour, and it was enormously fun to make.

Done entirely in Garageband.
