No one has asked yet what I will miss about Switzerland, possibly because it is obvious that I will miss chocolate, cheese and canals full of swans, but another thing I will miss is strolling outside to the sound of Fiddler on the Roof, the Ride of the Valkyries or other classical music being played by the small street bands and accordion players who appear almost everywhere in this country. It is as though Swiss streets come with a  soundtrack.
