Made it to the box office just after 5 to see what my chances were of getting a ticket. Got one in one of the last few rows of the orchestra section, finally, after a technical glitch with the computer. The guy selling me the ticket thought they would sell out by the end of the day, and he was making plans to slip in and out of the room while the event was going on because the staff weren't being allowed to get tickets for themselves!
Oh, and very specifically said NO PICTURE taking allowed!
