Very pretty!
Edit: "Very pretty!" is an understatement! I had only heard Part Of Your World till then and wasn't too impressed, but she got better and better! A Whole New World was more beautiful than I ever imagined it for her to sing and everything else was spot-on, too! I think it's great how obviously "live" her voice is and how her voice gets sung in over the few moments! Also, each song beautifully graduates to the next! And When You Wish Upon A Star is the perfect ending!
Alex is underrated I think.
