Cannavale cannot sing. I've heard him attempt to sing before (this was before his foray at the Tonys), and even if they hired Placido Domingo to be his vocal coach I still don't think there would be much to work with.
And yeah, the Tommy Tune/Twiggy thing made me raise an eyebrow. Tune has been openly gay for decades--it seems like another one of Riedel's inevitable factual errors, unless anyone can shed some light.
"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."
