VIDEO: Watch Control Room Split Screen Perspective of GREASE LIVE's 'Greased Lightin'

FOX's GREASE: LIVE was an undeniable hit last Sunday night, earning rave reviews, 12.2 million viewers and a 4.3 rating in the all-important A18-49 demographic. Much of the success had to do not just with the stars in front of the camera, but the many people behind the scenes. In the recently edited video, watch a split screen perspective of Associate director Carrie Havel working behind the scenes of the showstopping number "Greased Lightnin"!

Havel writes: "A lot of people have asked what it means to be the Associate Director on a show like Grease Live. Here's a peek behind the curtain. Every shot in the show was scripted by our director Alex Rudzinski. My job was to execute that plan. You hear me calling shot numbers and camera moves carefully coordinated with the music. #GreaseLive"
