How thrillifying that Cynthia Erivo and Ariana Grande opened the Oscars ceremony with a performance of songs from "Wicked." At the Dolby Theatre in Hollywood on Sunday, the two Oscar-nominated stars treated audiences to a musical history of Oz onstage and onscreen.

The musical opener kicked off with "Over the Rainbow" before segueing to "Home" from "The Wiz," as well as "Defying Gravity."

Ariana Grande and Cynthia Erivo opened the 97th Annual Academy Awards on Sunday, March 2, with knockout performances of "Somewhere Over the Rainbow" (Grande), "Home" from The Wiz (Erivo) and "Defying Gravity" (the two of them together). But a Wizard of Oz Easter egg embedded in the back of Grande's gown arguably stole the show.
