Oh Mariah...wow.  Most of us love the song "All I Want For Christmas is You", but I would guess most of us aren't going to be in love with her version she performed on NBC.  Mariah missed the the chance to pre-record her performance yesterday arriving 3 hours late, and instead, when she did it live, it left much to be desired.  Shreiky, off-key, and seeming like she was struggling to keep up with the song, this was a really rough performance for the once mighty Mariah.

If you want to hear the performance with just her vocals (it hurts), Deadspin has it posted HERE.
