HQ Video: Mariah Carey & Busta Rhymes perform 'I Know What You Want'...

The full video of Mariah and Busta's 'I Know What You Want' performance has been released in high quality, and I'm going to have to be honest here.
That little 15-sec clip doing the rounds highlighted the best part because the overall performance itself was a little rough around the edges. Did you hear her squeak at 1:20? Damn. 

I want to blame it on flu, but her voice has been a shell of its former self for the past few years now. Perhaps she's saving her vocal strength for the Christmas concerts because she's been sick, but if I paid money for tickets and she sounds like this... then yeah I wouldn't be a happy bunny either.
