A: The two men take inside hands and fall back a double; come forward turning single. Women the same.
B1: Circle left half-way; turn single left. Circle right half-way; turn single right.
B2: Double figure eight: ones cross down, twos move up the outside to start - at the end ones lead down and twos continue moving up to progress.
Sharp has four changes of a circular hey for the first 6 bars of B2 but Playford says "then the double Figure".
