Polkas bind the community together in central Wisconsin, where I grew up. The older people talk about the various bands in great detail, including the personnel changes and other historical minutiae, much like we talk about jazz. Romy Gosz is the Louis Armstrong of polka trumpet, for example.
A polka dance in a community in which it is valued, is one of the most fun experiences that one can have. A tremendous amount of beer, make that a nearly unbelievable amount of beer, is consumed by all, and the dancing, which takes some skill, gets very wild. The bands are cohesive and swinging. Often the best musicians in the area (in all genres of music) help pay their bills by playing in the leading polka bands on weekends.
If we were to read about a similar scene in some village in Africa, we would probably all fall over each other expressing respect and interest in the ethnic tradition and the indigenous music resulting from it.
