To all those who cry b/c it's not them onstage I have a secret to share - all actors do this. And those that are onstage cry b/c they want to be in that other part that so-and-so got. Its professional envy. But not envy in a begrudging way, envy in the way that makes you work harder.
Anyhoo-I get chills during One Day More every time i hear it.
Also, Defying Gravity, A Little Priest, Overture from Nine (that harmony!), and Only You from Starlight Express (I know, I know....)
