 In an interview with Barbara Walters set to air on tonight s 20/20 Julie Andrews confirms that throat surgery last year damaged her vocal cords. In a pre-recorded interview, Andrews told Walters that she is trying to remain optimistic that her voice will return: "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 , " she says.
