When Adele performs at the Grammys on Sunday night, in front of an expected audience of 25 million, she knows that many will be expecting her voice to falter. Although it was only four months ago that she underwent vocal cord surgery, the singer isn't worried about the health and strength of her voice, as she proves to Anderson Cooper in this "60 Minutes" sneak peek video.
In the clip, Adele sings 'Rolling in the Deep' a cappella. It marks the first time Adele's voice has been heard publicly since her surgery.
To see the full "60 Minutes" profile of Adele, reported by Anderson Cooper and produced by John Hamlin, tune in on Sunday, Feb. 12 (7:00-8:00 PM, ET/PT on CBS) before the Grammys.
