"I'll Know" is a great song- could you possibly have a guy sing it with you- because I think it might be a little hard to perform it on stage by yourself. If you can't get a guy to sing it with you, maybe you could sing "If I were a Bell" (also from Guys and Dolls) because it's really fun and easy to perform- you just act drunk!
