A1: Men take hands and fall back a double; come forward turning single. Women the same.
A2: R-hand star half way, turn single. Twos, followed by ones, cast down into line of 4 facing up, ones outside.
B: Forward a double and back, bend the line (all improper). Ones cast down into 2nd place and cross over, while twos lead up into 1st place, crossing.
Cecil Sharp's version in the first video finishes with the ones casting, the twos moving up, and all crossing. Pat Shaw's version in the second video (animation) does what Playford says.
