So, here is the handbill advertising the musical performance (without sets and dancers) that's happening this Saturday. JOSEPHS® is a part of the Fraunhofer Institute and seems to function as an interface with the general public. It has a really nice coffee shop with free WLAN (German for WiFi). The search for WiFi was how I found this place. The people there are so nice and through some conversations in my terribly broken German it became known why I was in Germany in the first place. German switched to English and next thing I knew we had a performance scheduled. Dumb luck was on my side that day! Here's a link to their website, but it doesn't seem to have an English version.
