From 2012, please enjoy you-know-who's hell-spawn and an absolutely jaw-droppingly good (and essentially unplugged) version of Dolly Parton's classic "Jolene."
Talk about torpedoing your preconceptions -- it would never have occurred to me that anybody who grew up on the Mean Streets of The Mickey Mouse Club could actually have any talent. And in my defense, I actually once sat through a Hannah Montana movie in a local Hell Octaplex.
In any event, I take back every nasty thing I've ever said or thought about this kid. Damn, that's just freaking terrific.
