Hi Jack, I think there is a problem with the progression in the mystery dance. The partner swing is on the ladies side, so B2 leaves people on the wrong side. Using a B2: Gents Allemand Left 1 1/2, Neighbor swing would fix it, but the dance still is a mystery. A few dances that have a progression at A1 and then the same A2 and B1 are: Hey in the Barn Chart Guthrie Improper A1 Neighbor Balance and Swing B2 Ladies Chain, 1/2 Hey Pinewoods Crossing Jim Kitch, et al Improper A1 Neighbor Gypsy 1 1/2, Circle Left B2 Circle Left 3/4 Ladies Roll Away (L to R, on side) Pass Through Across, Cross Trails* Pass your partner by the right, pass neighbor by left Pride of Charlottesville Seth Tepfer Improper A1 Neighbor Seesaw (Left shoulder DSD) Neighbor Allemand Left 1 1/2 B2 Gents Allemand Left 1 1/2 Neighbor Allemand Right 1 3/4 Southern Swing Steve Zakon-Anderson Improper A1 (new) Neighbor Balance and Swing B2 Ladies Allemand Right, Pass Partner by Left Gents pass by Right, Neighbor Allemand Left 1 1/4 Cheers, Bill
