16 bars of an upbeat song?

So I need 16 bars of an upbeat song for a theatre audition. Any suggestions? I have more of an alto range and can't go up too high. My broadway singing isn't great, but I can generally sing well. My favorites are Sara Bareilles, Colbie Caillat, but I don't know if "Love Song" or "Bottle it Up" would work for theatre. I also sang "I give myself very good advice, but very seldom follow it," in Alice & Wonderland, but that is slow. Thank you in advance for anyone willing to help.
