Total Equality:
A1 People on the right chain across (as ladies' chain) (3)
Same people meet palms to palms and push off backwards and slightly to the left (as in a ricochet hey) as the others step right behind them (2)
The others chain across, finishing meeting in the middle (3)
A2 Those in the middle (balance and) swing (8)
B1 Partner balance and swing and finish a random way around (8)
B2 Take hands in a ring of 4: balance the ring (2)
Pass through across, turning right to face back in (2)
Lines forward and back, sliding left one couple (4)
The B2 is quite cunning for a dance aimed at role swapping.
