Duet for a stinker

Ok, I have to do a duet with a guy who has a fantatsic voice, but the brains of a fish (a stupid fish) he picked Time To Say Goodbye - Sarah Brightman, Andrea Boccelli. But he can't learn it properly. I need a duet that is quite simple but a good one. U know what I wanted to do The Time Warp, go into the audience dance and have a laugh, but he isn't confident enough to do that UGH!!!. PLease help me as I am desperate. I thought maybe High Flying Adore as that has a prety simple melody. but help me!!! Hello by the way!

I agree with Old Fashioned Wedding from Annie Get Your Gun. He has the straight part, and you get the fun part, and can wipe the floor with him!
