I'm shocked. I was expecting a few 'rogue brothers/sisters' had overstepped the mark, but this involved a lot of people and a lot of organising and takes place in a lot of official places and during 'work time'. Incidently I would not want to be eating their sausages (01:52)!! :D
If somehow it were possible to time travel and show this to the people attending in the 60s/70s...
...actually it makes me chuckle to think of that possibility.
On YouTube in the recommended videos was this gem:
South Africa Bethel Dance Party
It really picks up around the 10 mins mark.
Enjoy!
