I just can't believe what I read here. We live in Europe, do we? Not in Orwell's 1984? On the other hand it reminds me on what England tried to do to the Irish some centuries ago when they tried to forbid to the Irish people to play their own music, to play their own instruments(the harp f.e. and the tradition of the bards, it's political and religious aspects) as a try to destroy the Irish culture and identity by these means. Fortunately the former paddies invented lilting and the musical tradition lived on.Seems a bit the same, doesn't it?
When people in Germany come together in pubs by chance and an unexpected session starts it may be the owner of the bar to stop them because he doesn't like it (and sometimes it's really the best to avoid serious damage of ears) but I doubt if there is any law against it. Anyway I'll try to make that shure and find out more about the juridical side of this subject.
I'll tell you about as soon as I know.
