It seems to me that the “Human Zendrum” — in which I took part, by the way — was more of a derangement than an arrangement. 😉
But really, one can pick up the necessary musical training with an evening course or two at any local college. Skating? That’s a bit more difficult and usually involves falling on one’s derriere a few times. But I can’t imagine that it’s hard to find a rink with basic skating instruction in Switzerland.
