The correct answer to this Carnegie Hall question is, of course, practice. My next guest has done that. More than Carnegie Hall, she’s sung in every opera house in the world she's wanted to sing in, save one. 

Gwen and I have known each other since we were children so I didn’t think she could surprise me. As far as her many accomplishments are concerned, the people she’s met, the places she’s performed, she didn’t surprise me. What did surprise me is her unfailingly positive attitude and the joy she still takes from music. 

Gwen has plenty of reasons to have a not-so-rosy outlook on life. But somehow she finds a way to remain a positive force in our universe. And we’re all the better for it.
