"Give Him The OO-La-La" by Cole Porter
It ought to be done rather fast and the lyrics which are very clever need to be enunciated within an inch of their life. There are many jokes within the song and many double entendres. The audience deserves them all.
Another thing, no one will know the song. Okay maybe a few, but not very many at all. You could stop a show with it and everyone will think its new when it was written in the late 30s-early 40s.
"If my life weren't funny, it would just be true. And that would be unacceptable."
--Carrie Fisher
