Can't Go Back demos?

[UndoingTheLaces]

I've totally been indulging in a fantasy of Lindsey and Stevie doing a live mashup of Can't Go Back and Wild Heart since Stevie's infamous Wild Heart dressing room performance has become such a viral sensation and she was singing to Lindsey's instrumental demo of Can't Go Back. Are there any other demo versions of Can't Go Back out there? Except for the instrumental demo, which is actually quite different from the final song, I don't think I've ever heard one.
