A Wiki site which anyone can edit lists Kelli O'Hara as appearing in The Merry Widow next year. Renee Fleming is the star of that production. I've read in the past there was some possibility of her appearing at the Met, but seems like she would be booked in different musicals for the next few years. 2014- 2015 Future Met Wiki
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
-John Guare, Landscape of the Body
I hope this is true, because it will be fantastic. It also lists Nathan Gunn in the production. They had such great chemistry in Carousel, and I would love to see them together again.
I thought she was great in Carousel, but that he was not so good, he's just not much of an actor. I think the Met's schedule should come out pretty soon.
