Youtube is a mishmash of videos, some very great to watch
Probably the most interesting that I saw was a video of Munktach from the 1930’s. It was various scenes from the town of Munkatch
It had the wedding of the Munkatcher Rebbe, It had a Mussor speech about Shabbos from the Rebbe, It had a shop scene from Munkatch , It had a Hora Scene and it had a bunch of Kids singing Hatikvah (With the original words that I didnt know existed)
It is sad watching the kids singing Hatikvah as you know in about 8 years (Not sure when the video was shot) all of them would be dead.
