I just love this quote though:
Long haired Morris dancing crew (Blackheath Foot & Death Men) in intensive training for Summer Festivals and Civil Insurrection narrowly escaped arrest after ejection from Woolwich Indian Restaurant due to the role of a meat cleaver in the performance of their traditional English dance
(International Times, 11-25 February 1971).
I can just see that happening.
Nearly 40 years later, we are still going strong and can be seen dancing out in Greenwich today, although probably without the meat cleaver. Details here.
