Song of the day: "Take me or leave me" from the musical Rent

In the television series Glee, two characters sing a duet of "Take me or leave me" in the episode "Comeback". This song is from the musical Rent, which I haven't thought about for a while. It is a rather catchy piece and features (what I think) is some kind of musical progression -- the key keeps changing.

MAUREEN:
Every single day,
I walk down the street
I hear people say 'baby so sweet'
Ever since puberty,
Everybody stares at me
Boys, girls, I can't help it baby
So be kind, and don't lose your mind
Just remember that I'm your baby

Take me for what I am
Who I was meant to be
And if you give a damn
Take me baby,
Or leave me

Take me or leave me

MAUREEN:
A tiger in a cage
Can never see the sun
This diva needs her stage
Baby, let's have fun.
You are the one I choose
Folks would kill to fill your shoes
You love the lime light too, now baby,
So be mine and don't waste my time cryin'
'Honey bear are you still my, my, my baby?'

Take me for what I am
Who I was meant to be
And if you give a damn
Take me baby or leave me

No way, can I be what I'm not
But hey, don't you want your girl hot?

Oh, don't fight, don't lose your head
'Cause every night who's in your bed?
Who?
Who's in your bed?
(spoken) Kiss pookie

JOANNE:
It won't work
I look before I leap
I love margins and discipline
I make list in my sleep baby
What's my sin?
Never quit
I follow through
I hate mess but I love you
What do with my improptu baby?
So be wise 'cause this girl satisfies
You got a prize but don't compromise
You're one lucky baby

JOANNE: Take me for what I am
MAUREEN: (spoken) A control freak
JOANNE: Who I was meant to be
MAUREEN: (spoken) A snob yet over attentive
JOANNE: And if you give a damn
MAUREEN: (spoken) A loveable droll geek
JOANNE: Take me baby or leave me
MAUREEN: (spoken) An anal retentive

BOTH: That's it
JOANNE: The straw that breaks my back
BOTH: I quit
JOANNE: Unless you take it back
BOTH: Women
MAUREEN: What is it about them?
BOTH: Can't live with them or without them

(overlapping)
BOTH: Take me for what i am
JOANNE: Who i was meant to be
MAUREEN: Who i was meant to be
And if you give a damn
JOANNE: And if you give a damn then
Take me baby, or leave me
MAUREEN: Take me baby, take me or leave me
BOTH: Take me baby or leave me
BOTH: (spoken) Guess i'm leaving, i'm gone!
