I thought she did really well. When you consider she originally only signed on to do the duet with josh groban then over the last few weeks she was roped into the others as well i think she produced the goods. Consider learning all those lyrics? She probably wasnt the best choice for that french song bcos of her accent but vocally she was top notch. Not many young mainstream female vocalists could have pulled it off to the same standard. I think she handled all of the songs really well. She toned down the riffing which is more suited to pop and rnb and she showcased an impressive vocal range. The control she showed in Look to Your Paths vocal runs were commendable. The only mainstream female artists who could have matched that are the likes of Christina. So yes all in all she did really well at Oscars especially when you consider the virtually non existent rehearsal time she had for any of the songs. Good on ya girl!!!
