It was the first time Adele has sung in public since throat surgery in early November and came at the request of interviewer Anderson Cooper. In the "60 Minutes" interview, she also talks about when she first realized there was something wrong with her voice and describes how she managed to communicate without speech.

The interview airs on CBS before the Grammys, where she's up for six nominations, including album and song of the year.
