Here's a march popular with flute players where I come from. I'm not sure where it came from originally.
I think the "pike" in question is the weapon variety and not the ingredient Olympic divers include to get more points per plunge. Are the extra points as compensation for any potential lacerations they might sustain if the pike bites them? Maybe the chlorine in the pool sedates it and stops this from being a risk anyway.
I played it a second time on a piccolo (or pikeolo) but got very self-conscious as people playing little flutes haven't always got on too well with my neighbours. Anyway, I think the tune suits the tiny treatment.
