I'd like to add one to my 2012 list: Mary Michael Patterson. She played Christine with spirit, sang like an Angel of Music, and gave the Phantom a longing look as she and Raoul departed. She and Norm Lewis played off each other perfectly. I saw two performances in the same day last August, and I preferred her matinee interpretation to Sierra's in the evening.
Audrey, the Phantom Phanatic, who nonetheless would rather be Jean Valjean, who knew how to make lemonade out of lemons.
