After failing to get a ticket to the evening rush ticket for Bandstand, I decided to take a shot in the dark and go over to Charlie (on 4/29). I got there around 10:25, have no idea how many people were sold tickets prior to that, but after about 2 minutes, they announced that they were out of matinee rush tickets. But I was indeed able to get rush for the evening.... center orchestra row J seat 106!! No idea how I managed to get a premium as a rush ticket, but hey, who am I to complain?!? They said they would run out of evening rush tickets about 2-3 people after I got mine.
