-Comment: Some probably Bavarian boys and men in black buckskin Tracht Lederhosen (pictured). I'm not sure about this title and only have some few scenes on VHS tape. But sure broadcasting was 1989 and edited by Hans Böhmler. I found only this TV series which is even still running (no entry at IMDb). One boy and girl are younger (in the middle) and at the end many young and old men in Lederhosen leaving the scene and walking to the right. Even not sure if they also dance Schuhplattler or only other dances. I only made some screen captures recently (without speaker plugged in). If I have much time I will check my old tapes again.

If you search for Unknown 1, I could solve it, see "Hahó, Öcsi!" (rating 3).
