From Gypsy, I'd probably have to go with You Gotta Get a Gimmick, with one of my favorites being "Dressy Tessie Tura is so much more demure-er / Than all them other ladies because"
As for West Side Story, I'd probably say A Boy Like That/I Have a Love, with this verse being particularly powerful
"I have a love, and it's all that I have.
Right or wrong, what else can I do?
I love him; I'm his,
And everything he is
I am, too.
I have a love, and it's all that I need,
Right or wrong, and he needs me, too.
I love him, we're one;
There's nothing to be done,
Not a thing I can do
But hold him, hold him forever,
Be with him now, tomorrow
And all of my life!"
I don't really know Do I Hear a Waltz? very well, so I can't say anything from that.
When I see the phrase "the ____ estate", I imagine a vast mansion in the country full of monocled men and high-collared women receiving letters about productions across the country and doing spit-takes at whatever they contain.
