"On The Rise" from Dr. Horrible's Singalong Blog. Look it up; it's amazing, and it's new, so there's not much of a chance that they'll have heard it before.
"Unworthy of Your Love" from Assassins
"Sirens" from Jane Eyre. (An underrated song, one of my favourites)
"Legally Blonde" from "Legally Blonde" (NOT the reprise)
"I'll Know," "Sue Me," or "I've Never Been In Love Before" from Guys and Dolls.
"All 'Er Nuthin'" from Oklahoma (It's funny!)
"The Song That Goes Like This" from Spamalot (This song is HILARIOUS, especially if it's performed correctly.)
"Point of No Return" from Phantom of the Opera (or "All I Ask of You," if that's more your cup of tea.) These are cliches, but they're still fun to do, and they have that magical ability of making almost any singer sound good performing them.
Too bad it HAS to be a guy and a girl, or you could do "Confrontation" from Les Miserables! That would be amazing!
Another fun one is the "Elephant Love Medley" from Moulin Rouge.
In my pants, she has burst like the music of angels, the light of the sun! --Marius Pantsmercy
