Need a Title and Artist(s) name...?

Question

I have very little to go on. The song goes something like this: Who do you, who do you, who do you, who do you think you are...Chorus: Baby, I'm crazy, Baby I'm crazy, crazy for you. We heard it at a drag show they were performing the song (if that helps). I swear I've heard it before, could be an old disco song re-vamped. I would appreciate any help, sorry I don't have much of the lyrics to go on.
