I should mention that these videos are from at least five years ago if not earlier and show the late, great Atlantis and the late, great Sankt Augustine-Meindorf club (a sister club to Bernds).
If you ignore the cheesy background music and the extremely tedious descriptions of German food, culture and FKK club etiquette, they can be quite entertaining.
Dexter Horn runs tours of these clubs for the linguistically, culturally and socially challenged.
