I have My Fair Lady auditions and need help SOON?

I have My Fair Lady auditions and need a song to sing. I'm a b with a wide rang but I need to sing something that is more in the Baritone area but at the same time I need the song showed my range. The description of what is needed is "Good singing range up to lower ranges of the tenor part." Oh and I am trying out for Freddy Eynsford-Hill.
