(S07E19) The big question coming into the results show this week, obviously, was who would make it through to the finals. That, on its own, was probably enough to get most of the crowd to tune in. The powers that be could have just banked on it and tossed any old random segment out there to fill up the first 50 minutes of the show. Some Jimmy Kimmel here... a highlight reel there... the numbers would have still been huge. Lucky for us, that's not what they did, at all. It was the biggest musical event the show has ever seen. Along with those big results, we saw performances from Leona Lewis, John Legend, Julianne Hough, and the Queen of Soul, Aretha Franklin. If that wasn't enough, reigning champ Kristi Yamaguchi stopped by to dance. It made for a fun hour. The results, and a look at all of those performances, after the jump.
