In den Bergen (in the mountains) is a traditional marching (or drinking) song - typical of what are called “Kneipenlieder.” A “Kneipe” is a small neighborhood bar where much local frivolity is to be had. And while it is technically a march, it works very well as a polka as well.
As with all of these Octoberfest Dances, everyone gets major time with the melody, there are interesting countermelodies and challenging “end-of-phrase” licks — and it is very danceable.
