I can’t come because of the too far distance and less time from Frankfurt, but I would like to recommend the „Lessons and Carols“-church service held in english language in Tübingen at the Stiftskirche next week, December 18th, at 7pm:
In the past years when I have been living in Tübingen I attended and took part also as a speaker in that special church service. It always was special. So if you have got time, visit and attend the church service. 🙂
