Wow, thanks for your very informative answer, drimal! :) :) I think it's very interesting how there are so many differences (in intonation especially) across dialects of German. I would like hear Luxembourgish one day, even though you say it is not a very melodious language! Australian accents aren't either really - we typically speak in a very "flat", nasal way.
By the way, I have heard the music (but not the words) for the Liechtenstein national anthem - I thought I was hearing the English one by mistake!
