Need some staging description? Thanks!

Hi all! There's something I've been wondering about. In the staging of the very final part of the Final Lair, when he says "You alone can make my song take flight, it's over now the music of the night" (sorry if I butchered the punctuation), does he say those lines to Christine and Raoul wherever they are off stage or does he say them out to the audience? I don't think the libretto says which. :-) And it's been literally decades since I could see the show in that kind of detail, so I don't remember the exact blocking!

At least in the original replica productions, it's typically done like this:

(To Christine, in the boat with Raoul): You alone can make my song take flight
(turns toward the audience): It's over now, the music of the night

Thanks Phantom On A Budget! Much appreciated! It's for a series of blog-posts, and possibly an essay, that I'm working on on the politics of the original stage-version vs the Gerik.
