Mr. President, Mrs. Obama. There is a photograph of you [hugging] that went viral, became the most shared photograph in the history of Twitter. How do you keep the fire going?

It would be nice to feel that we are a better world, a world of more compassion and a world of more humanity, and to believe in the basic goodness of man.

I didn't have a very religious family.

[President Obama] made so many promises. We thought that he was going to be -- I shouldn't say this at Christmastime -- but the next messiah.

To not sing with an orchestra, to not be able to communicate through my voice, which I've done all my life, and not to be able to phrase lyrics and give people that kind of joy, I think I would be totally devastated.

Because there are so many shows on and because I've been so hands-on - I've had a piece on almost every single week - I don't know how to cut back on that. You really can't.
