It seems Crystal doesn't approve of cellphones ringing in the middle of his performance of "700 Sundays". He politely told the morons to turn off their electronic leashes, got huge applause. The New York Post apparently called him a "control freak", as a result.
I know if I'd paid anywhere near this much for a ticket, I'd be royally ticked off (she said, doing her best to keep her language clean) to have it interrupted by somebody's bleeping tones.
I wonder if the Post's reporter might have been one of those anal apertures whose phone was ringing during the performance? That might explain their attitude.
