Well, there is a difference between making it through a song and hitting all the notes. At the performance I saw, and in all recordings I've heard, Ivey managed the former (and just barely). Not pretty to hear.
Victoria Clark was a great Sally at Encores, the rare singing actress who could handle the demands of the score and act the role with aplomb. Personally, I'd love to see Christine Andreas or even Marin Mazzie as Sally. Or Clark again.
"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."
