Ordinary Germans Social Dancing in the Weimar Era

This is a collection of snippets I found in various places of Germans social dancing in the late '20s and early '30s. The first, the Tango, is probably a home movie. It's taken from a BBC documentary on the Graff Zeppelin. The second and third were home movies found on the Internet Archive. The last is a Jewish wedding reception of unclear provenance found on YouTube. All were silent. I added music from the general era that seemed to fit.
