Lyte, honey, here's what u need to do...it's never good to do a song from the show are auditioning for, it corners you into one role, one which the director may not even be considering you for.
If you have your heart set on one role, ie Sandy, do a song that is done by a similar type character. For example, Sandy is a young, naive, "goody goody" ingenue type. Find some songs that fit that type
It's always better to do a song that you are comfortable with, shows your range and let the director do what he may.
Yes that's me. No, it's not a Rent homage.
