I think this is one of her best performances ever. Although she's not "superbelting", There's magic in this. Especially her falsetto at the end. Warm's your heart and gives you chills throughout your body. Her best falsetto is by far in "Vole" or "Fly" when she sings it live.
She's been lipping this song in this era... but she sang it live in Oprah... what a wonderful voice, I know she really can sing it but to preserve her voice, she must lip it for the other concert...
Luki Fern She doesn't lip sing in concert only on in show, to preserve her voice for concert. Especially when she's on day off where she isn't suppose to talk at all.
