At the time, it went something like this:
The Princess is on stage, dressed elegantly, primping herself for the Ball. Along comes The Magician, who magically produces a bouquet of flowers for her. They dance, and he takes leave.
The mood then turns sour, as her kingdom turns on the Princess, and she is booed off the stage.
Sad music plays. The body is brought downstage after a cloth is draped over it. The guillotine is removed. Then the Magician appears, waves his hand, and the middle of the cloth mysteriously starts to move, then rise on its own. The cloth jumps up and we see the Princess (head attached), as she and the Magician embrace.
I am also considering taking the Princess's head out of the basket after it is chopped off, and placing it in a small box. Right before she is resurrected, the box will be opened and shown empty. I don't yet have a method for the "head box." Maybe a tiny mirror box on a side table?
