Here's a clip of Adele's interview with Anderson Cooper, which airs on 60 Minutes this Sunday. She sings a cappela to demonstrate how her vocal chords survived recent surgery. Compare her to 99.9% of American Idol contestants, who also sing with no accompaniment and you'll see that this woman is a real singer.
The interview took place at Adele's new home in the London suburbs. It was her first public performance since the surgery and was first broadcast on CBS This Morning earlier today. She sings "Rolling in the Deep."
60 Minutes airs just before the Grammy Awards, hosted by LL Cool J, Sunday at 7 p.m.
