I just came home after a long walk through a park nearby (el Retiro). At a certain point, I started to hear an accordion melody, which I happened to know: « La Valse des monstres » from the Amélie original soundtrack, by Yann Tiersen. This would be no more than a nicety, if it wasn’t for the fact that the guy who was playing the melody was also… riding a monocycle! :-O. Some circus guy, I guess. I really enjoyed the moment.
