I agree with your point, but feel I must add a pedantic note on Morris dancing. It's a pretty niche pursuit in the UK, and I have seen Morris dancers in the US

I agree with your point, but feel I must add a pedantic note on Morris dancing. It's a pretty niche pursuit in the UK, and I have seen Morris dancers in the US (without even trying to). I wouldn't be surprised if the US has more Morris dancers than the UK.
