Adele is one of the biggest names in music right now. You can't go anywhere without hearing one of her songs. Just about the only place you won't hear her lately, though, is in concert. Last year she had to cancel two tours because of problems with her voice and because of that, she underwent surgery on her vocal cords. After months of recuperating, Adele is back.

In an interview with CBS's Anderson Cooper, he got her to sing part of "Rolling In The Deep" acapella that was featured on the Early Show on CBS this morning.

Adele will be performing on the Grammy Awards on Sunday night on CBS. It's all part of a bigger interview with Adele that will be on 60 Minutes right before the Grammy's.
