soprano warm up song request

I know that there are some singers out there reading this, so I thought I'd gather your wisdom. I'm always looking for good songs to sing as a warm up for choir - stuff that hits A and B above high C - so that I can actually sing my notes when I get there. I currently sing a lot from Camelot, Scarlet Pimpernel and a couple of other musicals. Do any of you have suggestions for good, high, but not too difficult songs to use for warm ups? And if anyone wants a copy of a mix once I make one, let me know :)

So I'm falling behind once again. Maybe listing things here will help:

-YarnZine!
-fabric for handmade
-CDs to Nikki
-Knitted stuff to zLana
-Birthday goodness and encyclopedia entry to EssEssEss
-20things
-City ATCs
-Artist Playing Cards
-Signs Zine contribution
-Mini Zines
-Book of Numbers and Letters
-Collage stuff to Samantha (whose nervousname I forget)

GAH. This is what happens when I go away for a weekend. That, and my craft room is in worse shape than usual. Luckily, I'll have 3 hours of Buffy (2 on F/X, one that I haven't seen, and the new one that I taped from last night) to sit in the craft room and clean and work.

I've been knitting up a storm. I'm a foot into a birthday gift for a friend, and working on size 15s, which means it shouldn't take too long to finish, even though the needles give me finger cramps.
