A1: Men right-hand turn. Do-si-do opposite.
A2: Women right-hand turn. Do-si-do partner, keep facing.
B1: Give far hand to partner - the one farther from the other couple, that's man's right, woman's left: balance forward and back. Change places turning the woman under (woman turns to left). Give the other hand: Balance forward and back; Change places turning the woman under (woman turns to right) into ballroom hold.
B2: Waltz round this couple 1½ times and face a new couple.
Based on Pat Shaw's “Waterfall Waltz” but without the objectionable (to me) moves that some people add to that! B1 modified 3-Mar-25.
In the waltz around you need to point out that the couples are rotating clockwise while going anti-clockwise round the other couple.
