Many years ago - 1966 - my wife and I, recently married, took a "Europe on $5. a day" trip. When traveling through Denmark's Jutland region we spent a few evenings in the cities of Aarhus and Aalborg. In one of those two cities, can't recall which one, we discovered that an American jazz musician was appearing at a local club.
Naturally we went to that club and were surprised to find that Ray Nance was performing. Ray backed by a local rhythm section did it all. He played trumpet, violin, and sang as well as doing some dance steps. It was a joyful evening that I have never forgotten.
