In the wonderful Speelklok Museum in Utrecht there is a room dedicated entirely to barrel organs.  I once wandered in there as a group of pensioners were being given a guided tour.  When the barrel organs began to play, couples formed to waltz around the room in a little impromptu ball.

Only written this year, Santa Lucia is the baby of the family and was brought to life by Steph’s ingenious barrel organ arrangement.  If, one day, pensioners waltz around a room to this song, all of this will have been worthwhile.
