While in Cologne we went to an Andre Rieu concert. We bought the tickets a couple of months ago so we could get them delivered to our home in Birmingham before we left on our trip. It turned out to be a sell out crowd of about 10,000. We had great seats on the floor on the end of a row. This is important because during the concert the orchestra would play a waltz and if you were able to get up you could dance in the isle. So we got to dance to Andre Rieu playing a Strauss waltz.
