The B2 could be W DSD 1.5, although I like the allemande for the connection for brand new dancers. I specifically chose the left hand to leave the women facing towards their new neighbor.
I know it's really close to a bunch of other stuff. B2 could be C L 3/4, balance and pass through; or chain to left hand star à la The Nice Combination; etc.
Barring it already having been named by someone else, I'm going to call it "Having Fun with PAM" to keep track of it in my box; since I just got back from the fabulous PAMFest (Peacham Acoustic Music Festival).
Thanks.
