A melancholy figure with a concertina, he's best known for showing up in Paris to sing about the city's hardships and the struggles of ordinary people there.
Fair warning though: there's a historical problem with this whole setup. Concertinas didn't actually exist until after the French Revolution, so if this character is supposed to be from that era, the instrument doesn't fit the timeline.
