What's a great song vocally for a mid- ranged male to sing?

I have a few auditions for a singing program coming up, and I need to come up with some really strong songs to sing. The highest note i can hit comfortably is a high F flat, so it cant be like a queen song or something absurdly high. Can anybody tell me some really good male vocal songs? None of the modern pop songs, I'm looking for something classic, like a big show stopper. Any help would be greatly appreciated!
