NBC celebrated Wicked [1]'s 15th anniversary with a Halloween [2] special on Monday night, and it was nothing short of emotional [3]. Not only did the special include some star-studded performances — including Ariana Grande's rendition of "The Wizard and I" [4] — but it also featured a few very special Wicked reunions. After Idina Menzel and Kristin Chenoweth [5] finished cohosting the special, they ended the night on a high note by bringing out their fellow Elphabas [6] and Glindas to sing the musical's final number, "For Good." As the ladies held hands on stage and sang about sisterhood and friendship, it was hard not to shed a few tears. OK, a lot of tears! Even Chenoweth got a little choked up during the performance. See the endearing moment ahead.
