On the Today Show, Alfie Boe performed the tittle song from the show, and it was said that he is leading the National Tour once the Broadway run ends. I guess he'll only be with it for a little, since it was also announced he's opening the London Production.
Bwaydrummer31 said: "It's certainly been confirmed on their website. And I'm pretty sure Kelsey Grammer and Mr Boe were announced to open it.

No that was just an article in the daily mail as who producers were looking at. And whilst it's clear they are making london plans, nothing official has been announced like dates, theatre or cast.
