I've searched in vain for a quote by Albert Schweitzer. As I remember it, when someone asked him how he could stand having to play on an old, out-of-tune upright piano in the middle of Africa, he replied something to the effect that when you're playing Chopin, the instrument doesn't matter. Could be that I just rembered it wrong, but I don't think I completely made it up. Anybody else heard of this one?
