Broadway duets for 2 women?

So if gilana and I were going to do a duet for First Church's Broadway Night fundraising evening... what could we do?

There just aren't that many Broadway female/female duets that I know of (and gilana claims to know even fewer). But I was thinking "Marry the Man Today" from Guys & Dolls. Or maybe "Mister Snow" from Carousel. There must be something good from Chicago, but I don't know it well enough or have it to hand.

Ideas, anyone? Either alto/alto or alto/sopranoish is okay.

P.S. Tonight's auditions were fun! And not too terribly nerve-wracking!
