Let Wicked's'For Good' Restore Your Faith in Humanity 

The beloved musical Wicked, with its massive appeal to LGBTQ audiences, celebrated its 15th anniversary Monday with a concert of songs from the blockbuster Stephen Schwartz musical. NBC's A Very Wicked Halloween featured several show-stopping performances, but it culminated with the original Glinda (Kristin Chenoweth) and Idina Menzel (Elphaba) and dozens of other good witches who came after them belting "For Good," the show's tearjerking ode to female friendship.

Earlier in the special, on a set designed to evoke the Emerald City, Chenoweth and Menzel sang their respective solo hits from the show with "Popular" and "Defying Gravity."

Other heavy hitters appeared, like Ariana Grande with a rousing rendition of "The Wizard and I," while Adam Lambert and Ledisi blew the doors off the venue with "As Long as You're Mine." Meanwhile, the a capella group Pentatonix took on "What Is This Feeling?"

But the real showstopper of the night, and a panacea of sorts at a time when the news cycle is tough to take, was the feel-good "For Good." Chenoweth and Menzel kicked off the song hand-in-hand but were soon joined by more than a dozen Elphabas and Glindas that followed them on Broadway.
