Definitely loving the BOY idea w/guitar spotlight, etc. It would really allow her voice to be the focus which is all you really need for an incredible performance. However, I chose other cuz I have to say even though I doubt it would happen, a two song set starting with BOY and ending with HEAR ME would truly be amazing.

Take the build up of emotion with BOY and then let KC really rock the house down with Hear Me and I think you would have a performance that all the people would be talking about around the water coolers the next day.
