What is good audition song for Joseph and the Amazing Technicolored Dream Coat?

I am auditioning for Joseph and the Amazing Technicolored Dreamcoat, my first musical in Years. Although, I've maintained my voice and sing daily- I'm out of touch with popular show tunes, that aren't overdone. The role im going for is the Narrarator. Most reviews and suggestions I read say this show is upbeat so a good audition piece would be something similar, upbeat. I was thinking of singing: Hero- Mariah Carey (I know, slow, not upbeat & overdone but i can really Belt it out and shows my range well) or Sharpay Evans [Ashley Tisdale] - New York's Best Kept Secret a href="http://www.youtube.com/watch?v=vogz6FAEqn4" rel="nofollow"http://www.youtube.com/watch?v=vogz6FAEq…/a I stumbled upon this movie on Disney Channel, Sharpays Fabulous Adventure (its about a charachter from High School Musical goes to New York in pursuit of her broadway career. i heard this song and loved it, what do you think?) or Dianne Reeves- Better Days a href="http://www.youtube.com/watch?v=B09HYFehZ5c&feature=related" rel="nofollow"http://www.youtube.com/watch?v=B09HYFehZ…/a (my mom sang this song to me as a child, I love it and know it by heart) So, Has anyone else done this show before, Joseph and the Amazing Technicolored Dreamcoat? What are some good audition songs for a female auditioning for the Narrarator? Thank you =]
