Stevie Wonder delivers the new collaboration entitled “Faith” featuring Ariana Grande for Illumination Entertainment and Universal Pictures’ Sing, it was announced during Grande’s interview on The Tonight Show with Jimmy Fallon last week. The song will be available soon via Republic Records, as well as on the upcoming release of the Sing Official Soundtrack Album. Sing opens in theaters everywhere on December 21st.

“Faith” unites Academy Award- and GRAMMY Award-winning Stevie Wonder and multi-platinum GRAMMY Award nominee Ariana Grande. Produced by powerhouses and multi-GRAMMY Award-winning songwriter/producers Ryan Tedder (Adele, Beyoncé, U2) and Benny Blanco (Rihanna, Ed Sheeran, Katy Perry), “Faith” marks the first song that Stevie Wonder has contributed to a film in more than 25 years.

“I’m featured on this Stevie Wonder song, man. That’s like, ‘What?’ I’m like done now. I’m good,” she tells Fallon. “Not only did I get to sing with him, but we were in the same booth so it was like Stevie and me were like arm in arm holding hands in the booth, singing together, laughing and having a good time.”

“Not only did I get to sing with him, but we were in the same booth.”

Set in a world like ours but entirely inhabited by animals, Sing stars Buster Moon (Academy Award Matthew McConaughey), a dapper Koala who presides over a once-grand theater that has fallen on hard times. Buster is an eternal optimist—okay, maybe a bit of a scoundrel—who loves his theater above all and will do anything to preserve it. Now faced with the crumbling of his life’s ambition, he has one final chance to restore his fading jewel to its former glory by producing the world’s greatest singing competition, even if the prize money isn’t exactly in the bank yet.

Five lead contestants emerge: A mouse (Seth MacFarlane) who croons as smoothly as he cons, a timid teenage elephant (Tori Kelly) with an enormous case of stage fright, an overtaxed mother (Academy Award Reese Witherspoon) run ragged tending a litter of 25 piglets, a young gangster gorilla (Taron Egerton) looking to break free of his family’s felonies, and a punk-rock porcupine (Scarlett Johansson) struggling to shed her arrogant boyfriend and go solo. Each animal arrives under Buster’s marquee believing that this is their shot to change the course of their life. And as Buster coaches each of his contestants closer and closer to the grand finale, he starts to learn that maybe the theater isn’t the only thing that is in need of saving.

Featuring more than 65 hit songs, Sing is written and directed by Garth Jennings (Son of Rambow, The Hitchhiker’s Guide to the Galaxy) and produced by Chris Meledandri and Janet Healy. Released by Universal Pictures, Sing arrives in theaters for the holiday season on December 21, 2016.
