NBC's upcoming A Very Wicked Halloween concert special is the stuff of magic. Celebrating the musical's debut 15 years ago, the televised concert will feature former and current cast members — including, of course, the original Elphaba and Glinda: Idina Menzel and Kristin Chenoweth — as well as a few other famous faces, like Ariana Grande and Adam Lambert.
Ahead of A Very Wicked Halloween, Grande shared that she would performing "The Wizard and I," a solo number performed by Elphaba. On Instagram, Grande wrote, "Honored to be included in this celebration of 15 years of my favorite musical of all time. Wouldn't miss it for the whole universe."
The rest of the cast has yet to announced which songs they will be performing; however, it's likely that Chenoweth will delight viewers by performing "Popular," and we're hoping she reunites with Menzel for "Defying Gravity." For now, it seems we'll just have to wait until the concert airs on Monday, Oct. 29.
