What Did Andrew Lloyd Webber Call Sierra Boggess?

At the Phantom of the Opera 25th anniversary, Andrew Lloyd Webber turned from Ramin Karimloo to Sierra Boggess. Hadley Fraser remembers the words as thanks, and then a dedication: you are my Christine for the twenty-first century, and I could not be more proud of you. Boggess already had a history with Christine, which is why Fraser says the line landed. He sets it beside the Phantom lines Webber had just given Karimloo. The speech, as Fraser tells it, is short. The sentence he keeps for Boggess is that Christine line, spoken at the end of the night rather than in a rehearsal note.
