Earlier this month I saw and greatly enjoyed Love and Friendship, the adaptation of Jane Austen's short epistolatory novel Lady Susan. There's not actually a dance scene in the original story, but they squeezed a brief one into the film. I'll defer full commentary on the scene until I can get the DVD and watch it a couple more times, but the brief version is that it was an odd and, as far as I know, ahistorical variation of Sir Roger de Coverley in which partners stood alternately proper and improper, resulting in lines that alternated gentlemen and ladies and diagonals that involved two people of the same gender. You can see it for about a second at 1:26 in the trailer here.
While I'm waiting for the DVD release, I'll free-associate to another country, era, and dance. I promise, this does have some connection to Love and Friendship!
