I have uploaded almost the complete last (4th) episode of this Bavarian 2010 documentary. Some boys in traditional clothes. Lederhosen (and Schuhplattler) only a very brief scene at the end (at 39), which is a summary of the previous episodes (I don't have). Boys starting at 18 minutes. Another scene a bit later at 21. Also altar boys (white/red).
Some good scenes. Maybe rating 5-6 for the other episodes.
