Plot hole?
In the first concert, when St. Clair checks to be sure that every ticket goes to a "music lover" (read "fan" of Miss Jenkins), the actor friend of St. Clair's wife, who barely managed to get a ticket for himself and had to swear to be kind at the concert, shows up with a bunch of friends, who he says are "music lovers". St. Clair doesn't stop them...he just says " I'll be watching".
I found it strange. Was I wrong?
