So our suspicions that Mariah Carey's Idol performance wasn't exactly as we were led to believe have kind of been confirmed with the surfacing of the video below. (Yes, I know, I was too chicken to say it in the post, but believe me when I say I spoke to a friend about it!)
Supposedly taken during the recording of the medley, the video clearly shows Mariah's belting range isn't quite as pristine as the rendition that aired on Idol wanted us to believe. It sounded particularly coarse and clumsy during the My All section of the medley.
However, it's still not clear whether the aired medley was a composite of the reported three takes; or if it was actually a cut and paste job of old/pre-recorded vocals. I suppose it would be less damaging if the they were all from the night- regardless of which take they happened in- but I guess we'll need to wait until (if?) the other renditions are released before we can really judge either way.
