2 chords: 1W & 3W interchange (M: 1,2,3; W: 3,2,1)
1-8
All set | Circle6 ½ way L ; 1c followed by 2c+3c cast cclw (M up, W down) to invert set | all cross LH to original pl
9-16
1c+2c cross RH on diag while 3c set | 3c+1c cross LH while 2c set ; 2c+3c cross RH while 1c set | 1c+2c cross LH on diag while 3c set (Mside: 3M,1W,2W; Wside: 2M,1M,3W)
17-24
All cross RH | 2c followed by 1c+3c cast cclw to invert set ; Circle6 ½ way R | all set (in same places as [16])
25-32
1W+3M+2M & 1M+2W+3W RHA{3}, 1c lead LSh Snakes{2} to change ends, LHA{3} in same groups. In the last bar(s) of the LHA 1c dance out ends & cast to 2pl, 2W & 3M (2nd in Snake) end in 1pl/3pl own sides, 2M & 3W (last in Snake) pass LSh to other end (M: 3,1,2; W: 2,1,3) NB the instructions are not clear about the final progression or how it is achieved. The above is a working interpretation.
