Twice through as the middle part of a longer display.

The original instructions for bars 15-16 say 1st half turn as 4th couples turn once round into promenade hold so both have the men on the left for the half reels of 17-20. Then 1st couple need to cross out and cast while 4th couple do not cross but just divide and cast in bars 21-24. However the team here have both 1st and 4th couples doing half turn in bars 15-16 so that 4th couple have the woman on the left for the half reels and then both cross out afterwards.
