Clog dancing was common in Lancashire mill towns when people wore clogs as work footwear. I remember their clattering on hard pavements when I was a kid. I also witnessed a clog fight, when two men's legs were tied to each other with a length of string and the ankle kicking commenced! The loser was the one who gave way first.

One of Britains's champion clog dancers was an ex music hall/variety dancer called Sam Sherry, a lovely man - dancer and musician - and occasional performer at my local folk club in Lancaster in the 1960s. He was one of the Five Sherry Brothers, who did amazingly acrobatic dancing while playing various instruments. And a very funny singer of humorous songs.
