At this point anyone that is questioning whether Hamilton will do well in London isn't paying attention. There hasn't been this much hype for a musical in London since Book of Mormon and we're still 11 months away. I can't go to the theatre in London without hearing someone talk about it. The Hamilton Mixtape was also #3 on UK iTunes this week.
Next to Normal is unfortunately a different matter but it at least deserves a run in a fringe venue. If we can have Side Show and Grey Gardens, we can have Next to Normal.
