dirac, thanks for that link. Some excellent reviews and comments. Definitely worth reading.
phrank, thanks for the video of "The Goblins. McRae does seem to have some of the necessary style. He got excellent reviews for his dancing of the Mad Hatter in Wheeldon's Alice, so has the advantage of knowing the choreographer well.
I Googled and came up with this article (March 15, 2013) from The Guardian:
The careers of countless British actors demonstrate that good training and hard work can allow you to acquire all sorts of "American" accents. All you need is a good coach, and London probably has plenty of those. But can he sing?
Here's part of Judith Mackrell's commentary on the video.
McRae looks like a Broadway natural, but you can see the classical dancer at work in the easy, graceful counterpoint of his arms and upper body, which acts as kind of jazzy épaulement to the footwork at 3.29 and 4.11 as well as the actual ballet moves, not least the expertly controlled drizzle of pirouettes at 4.20 that are worked into his routine.
