2017: Alte Donau | Old Danube. Playing jazz in the open air at the Bauer-home on the banks of the river

A relatively hot August afternoon in 2017 had us all convene at the Bauer resort home on the banks of the "Old Danube" in Vienna. There, after extensive food and drink consumption, we decided to do some jazz under a tree. Hartwig is leaning against a big shadow-spending tree, while playing "On the sunny side of the street".
