The Britannia Coconut Dancers from Bacup in Lancashire do their really quite strange thing. For the purpose of this 1930 film they have omitted a traditional part of their costume, i.e. they haven't blacked up, although I'm pretty sure this is a concession to technology rather than political correctness. They still dance every year, by the way (well, not this lot, they're all dead, but the current 'Nutters', as they are affectionately known). They even have a website where I purchased a tea towel.
