I was recently watching "Mythbusters" and they actually had a concertina on it!
For those of you who know the show, it's not what you think
For those of you who don't know the show, the premise is this: two guys (whose "day job" is creating movie special effects) try to prove or disprove urban myths. Not like Bigfoot or alligators in the sewer, more like "does putting sugar in your gas tank really kill the car?" or "can you really be sucked down into the water in the wake of a sinking ship?"
Anyway, the myth to be "busted" in this episode was "which uses more fuel, heat or air conditioning?" and they had to fill these two huge tanks with fuel. Apparently a crew member or friend came by to watch, and decided to play his concertina wile they worked.
It was a 20-button, probably a Hohner, judging by the wooden ends and large white plastic buttons. He was doing some nifty cross-row fingering, and it sounded to me like the tune he was playing was "Winster Processional."
Wonder what kinds of myths they could bust about concertinas???
