Oh I see, that's quite a story to tell!
I can see the looks on those East Berliners right now haha, kinda scruffy, a strange mix of things & styles...
Ever come across the term "Die Krufties"? I've been to WHT Treffen in Leipzig 4-5 times, a totally wild festival that originated from that bunch.
And also the DDR had a real American Indian phase in the early seventies, just like the West...
