Hi Chris, Peter Amidon here. Here are two dances that have the opposite couples sashaying in, although neither dance has exactly what you described: Willow Tree Formation: 8 or 10 couples (it also works with 9 or 11, but not quite as well). Let's say it is 10 couples: Top five couples are the 'Ups' and bottom five couples are the 'Downs'. Music: If you are doing the strip the willow figure, then you can use the Willow Tree medley on Chimes of Dunkirk CD or the music in the book. Otherwise, any jig or reel. Al: Top couple sashay to bottom. Top gent leave partner at bottom and sashay back up with bottom lady. A2: Bottom couple sashay up with Top gent's partner, and sashay back to bottom with own partner. B1/B2: Top and bottom couples strip the willow to the middle; Top couple with the 'Ups' and bottom couple with the 'Downs'. (Or the outside couples simply sashay to the middle of the set). When they reach the middle, same two couples make a 'House' of four arches: two side arches and two head arches. C: The remaining 'Ups' cast down and the remaining 'Downs' cast up. When the meet someone at the side, take their hand and go with them under the side arch. Then, inside the house, take partner's hand and go out the appropriate 'Up' or 'Down' arch and back to place. To repeat the dance, the Arching couples drop their hands and step back to their new places in the middle of hte set. The new top and bottom couples lead the next time through the dance. You can replace the strip the willow figure with the outside couples simply both sashaying into the middle to make the four-way arch. Intersection Reel from Warren Doyle adapted by Peter Amidon formation: Four longways sets laid out like a giant X. The head couples are the ones closest to the corners of the room. The bottom couples are the ones in each set closest to the center of the room. Between the four sets is a space that I will call 'no man's land'. A1 (16): Each of the four sets take hands in a ring and circle R (8) Each of the sets circle L (8) A2 (16): Dosido partner (8) Two hand turn partner (8) B1 (16): Top couples in each set sashay down through their own set, through 'no man's land' and up through the middle of the opposite set till they get to the top of the other set. B2 (16): Active couples sashay to the bottom of this new set they are in (not back to their original set). (8) Long lines forward and back. (8)
