POLKA MIXER
(Marion Rose, from "Step Lively 2")
32-bar polkas
Circle of couples in ballroom position, pointy end toward center.

A1: 1 polka step leaning in, 1 polka step leaning out.  Repeat with vigour.
    With four polka steps, a quarter-turn each, turn once round as a couple.

A2: Same again, then let go of the pointy hands and open up to join hands in
    a large circle.

B1: Circle goes forward and back
    Partners two-hand turn and reform the circle.

B2: Forward and back
    Partners bow, walk past each other passing right shoulder.  The next
    person is your new partner.
