It is possibly Swedish, I forget. I thought it was Swiss, but I haven't seen it in a long time, and it DOES have Ingrid Steeger.

Googled it, it's a Swiss and West German co-production.

Sorry, my comment was somewhat vague. I meant that I could understand them, and therefore they probably weren't Swiss actors. Sounds like a northern dialect.

Ah, gotcha. Not all of the bands are Swiss. Birth Control were German I think.

Switzerland, Sweden, same thing.
