Unofficial: On 2nd turn, 4c has an easier start if 1c+3c+4c dance a 3c Poussette
On 2nd chord, 1c & 2c cross to opposite sides (1x,2x,3,4)
note: 3c does not move on bars 1-8.
In 17-32, the corners traditionally set one bar to the person you just passed, then one bar to the next person to pass. In a variant for [19-24] 1c turns BH in PdB.
