I like Halvah. House seats for Broadway shows are held by actors, the director, the choreographer, the producers, the conductor and I'm sure others. They must reserve the use of them forty-eight hours or the box-office lets them go, which is frequently why you can walk up to the box-office on the day of a show (around five pm) and get great seats. If all the house seats are gone, they do keep an emergency pair until just hours before curtain for the producer. For example, I sat in Mr. Macintosh's seats for Miss Saigon when I saw it, thanks to Mr. Maltby.
