There is a cancellation line where you pay the rate of the seat that is cancelled, or in some cases, get stair seats (which are less than $85, but more than $20 if I remember correctly)... The cancellation line is essentially the rush, since the show is fully sold out.
I did the cancellation line for Perestroika this past weekend. Regular seats are $85 and stair seating is $40.
"All the world's a stage,
And all the men and women merely players:
They have their exits and their entrances;
And one man in his time plays many parts..."

January 30th is the final performance for Robin Bartlett, Robin Weigert, Zoe Kazan, Christian Borle and Zachary Quinto.
