[music is my life!!!]

Hiya! I'm new to the forums and i've got an audition 4 a concert for which i've practiced "I Know Things Now" and "Moments in the Woods" from ItW. I know what i'm doing musically but i'm not really sure about the acting part of it.
We're doing Oliver! as our next show which is in November. I'm interested in the part of Charlotte/Bet so i'm stuck for choice if they ask which one i'd prefer to do... HELP!!!!
Btw i'm a mezzo/alto and my range goes from about low Eb (below middle c) to Eb (above the treble clef) and i'm strong from low Gb toD (on the stave) and i belt upto a fourth space E.
I'm very musically inclined and i'm also auditioning "How do you solve a problem like maria" and "i just can't wait to be king" but i know i'm not gonna get those songs...
Sorry about all the background info, i'm just stuck... which leads me to my first problem... HELP!!!
This is embarassing...
If you cud PM/email me or even post on here, i would really appreciate it.
My audition's on SUNDAY!!! HELP!!!!!!

[music is my life!!!]

Back again! my audition for the concert's tomorow and i'm sorta nervous/excited about it. Please let me know about which song would be better to do on my part.
Any advice would be very much appreciated!
I'll try to post which song i got asap.
Thx!
