Auditioning for 25th Annual Putnam County Spelling Bee

Spelling Bee is a very character based show, so you're probably going to want a comedic, heavily characterized song. A song from Drowsy Chaperone or Avenue Q would be suitable; however, if you wanted to show off some more range while still showing your acting ability, I highly recommend Santa Fe from Newsies. this song is high on emotion but it does get rather high. It gets to an A4 (a few semitones under the Top C you mentioned but this would have to be in chest voice, not in falsetto) and it is held for quite a long time. If you can pull it off, it's a great choice but don't sing it if you can't sing it well - Drowsy Chaperone is full of songs that are suitable for an audition for Spelling Bee
