I've seen such a variety of buskers' instruments on the boulevard near our home: keyboard, trumpet, harp, cello, saxophone, violin, bucket drums, concertina, guitar, ukulele. I think this is the first accordion I've seen. This young man was really into his music - it had a Gypsy sound to it, a sort of haunting minor key tune. I heard him start to sing as I crossed the street; I'm sorry I missed that.
