audition help!!! Shrek and Hairspray

Hi everyone! I am auditioning for Hairspray in the next few months and might audition for Shrek next fall. I am going for Penny or Amber in Hairspray and Fiona or Dragon in Shrek. My top songs are Suddenly Seymour for Hairspray and The Witch(Big Fish) for Shrek. Any other suggestions? I am 20 years old and a soprano one but I have a decent alto range as well.

Thanks!

Hi! First of all break a leg on the auditions! Fly, Fly away from catch me if you can is an excellent choice. As well as Safer from First Date! :)
