Or Yellow Submarine, according to my favorite folk iconoclast, Dudley Laufman.
I dance for the friendships, for the connection to the community, and for the music. If I could play well enough to accompany instead of dance, I probably would! My team likes to bash sticks and we also wave hankies (Fieldtown and Headington, for those who know what I'm talking about!). We also like feeling connected to an old tradition in a fairly young country.
Besides, it's the only activity I've ever engaged in where a passerby looked at us dancing and said, "Wow, what great muscle definition!"
