OBC Rent on the I'll Cover You (reprise) the last line the choir sings "Seasons Of....loooovvveee" with Collins in the background.
OBC Phantom of the Opera: Brightman's "soar" on the "Raoul, I've Seen Him" track.
OBC Les Mis: Red and Black, "the color of despair." The way he hits despair...wow
When Headley joins in the song Elaborate Lives in Aida. "We...all...leeeeaaddd such elaborate lives." Beautiful.
Those drum beats that come in before Sherie starts singing "Oh, now I believe in lookin'" in My Strongest Suit, Aida.
Aida, again: When Sherie sings "Oh, I Know the Truth" and she kind of holds the "I" for a country rock feel.
Little Women: In The Fire Within Me, the part where the tune changes back to the melody of Astonishing and she reprises it.
Little Women: Some Things Are Meant to Be. That little pause then "All my life I've lived for loving you...Let me go now." Breaks my heart every time.
There's more, lots more, but I'll continue later :)
"I haven't got a pail."
"Find your grail, your GRAIL!"
"But it's not missing. It's right on the counter where it's supposed to- defying gravity, my giant cup's gone!"
"Five hundred, twenty-five thousand, six hundred minutes. How do you measure... measure a year?"
"How many times do I have to tell you, it's five hundred twenty-five thousand, five hundred and eighty-five point thirty-two minutes. You will never graduate if you keep basing your math on showtunes."
"You ruin Broadway for me."
"As well I should."
