I haven't seen this posted yet - sorry if I'm wrong. NYCB is having a Jan. 22 celebration of Balanchine's birth. Some events are free others not. I've gotten tickets to the 10:30 showing of the Balanchine documentary (free but you need a ticket), a matinee performance (tickets are on sale) and an onstage class of SAB students taught by Peter Martins (free but you need a ticket). I didn't purchase tickets to the evening performance. http://www.nycballet.com/ticketing/2011/balanchine.html
