Whats a perfect audition song?

I am auditioning for Sweeney Todd in a few weeks and I need a song. I know Into the Woods songs are recommended, but the director just finished a production of it and it would be extremely uncomfortable for me to sing from that show. I want to get the part of Toby. I am a girl so I need a song that doesn't leave the director thinking I can only portray a girl. (P.s. I am an alto but I can sing some soprano)
