A1: First couple join both hands, chassé down center (4) , heel, toe, heel toe with man's left foot, ladies right (4), chassé back up (4) and cast off unassisted into second place, second couple moving up 
A2: First couple turn contra corners 
B1: All balance and swing partners, end swing facing up 
B2: All chassé four steps, men to their right, ladies to their left, men passing behind partners (4), turn to face partner, move towards each other, joining hands in a circle of 6 (4), circle left halfway (8)

I modify the B2 1-4 into balance together, away and swap with partner (top couple, California twirl, others rollaway)
