Audition songs

Okay so I have been mullng over what song to sing for my Music Man Audition on Jan 4th. It has been a really tough decision. It has come down between two songs. Somewhere That's Green from Little Shop of Horrors and Roxie from Chicago. I have been singing along with both of them on my ipod and I think both of them would be good songs to use. Does anyone know if there are karaoke versions of these songs I can download so I can practice them without lyrics?

I am kind of more partial to singing Roxie because I want to sing something more upbeat. If I wanted to sing a snipit from each song would it be possible to do that? What do people think of that idea?


Update: I have decided not to sing Roxie anymore because there are few high notes in certain part of the song that I can't hit and I just can't make the song work. My back up is You're Never Fully Dressed Without A Smile from Annie. The best thing about using this song is that I do not need to order sheet music because I already have it.
