"Last Midnight" is possibly my favorite bit of the whole show.

You're not good, you're not bad,
You're just nice.
I'm not good, I'm not nice,
I'm just right.
I'm the witch.
You're the world.

Completely agree. In the recent Broadway revival with Vanessa Williams, those lyrics were actually changed, which made me want to tear my hair out. It changed to (singing to the baby):

You're so pure
But stay here,
And in time, you'll mature,
And grow up
To be them,
So let's fly,
You and I,
Far away.

I'm the hitch,
I'm what no one believes...etc.

The end is changed too to...

I'm leaving you alone,
Squirming in the mess that you've made.
Fix it on your own,
Time for me to go, I'm afraid.

Back to what I know,
Back to long ago,
Safe inside the world that I'm from
Better ugly and spurned
With my powers returned--

And I fear, midnight's here.
Time to disappear...
Mother here I come!!!

I think Sondheim should have left well enough alone and kept them the way they are. The original is so much more powerful and meaningful, whereas the new lyrics seem rather trite and dumbed down.
