"The ladies chain in Contra requires the man to support the woman behind the
waist with his right hand, when she is turned back to face the center and I
do not think the man dances behind the position but waits for lady to come
to him. But I am not a major Contra dancer, so i may be incorrect about the
mans' movement or lack of."
The man simply steps to the side or, more specifically, into the woman's
position, so as to be better situated to receive the woman's left hand.
