As a founder member of Hexham Morris Men, still dancing with them 25 years later, I plead guilty, but with extenuating circumstances. (I was persuaded to attend the inaugural practice as reserve musician, but as there were two musicians and only five dancers present, I got drafted.)
Seriously, though, it's been a heck of a lot of fun, and I'd recommend the Morris to anyone as a good way of keeping fit - think of it as jogging in fancy dress (and with a few beers and a song or two afterwards as a bonus).
Wassail!
