I don't know if SUFFS would be received the same way in London as it did here. That said, Hamilton continues to play there and that's a VERY AMERICAN musical. As Jordan mentioned, they are more likely to get the UK version, Sylvia.
For the musicals that did not get nominated for Best Musical, How to Dance in Ohio is scheduled to premiere somewhere in the UK next year. Days of Wine & Roses could, but it's not likely. With the Notebook having a growing fanbase, I think that could have a chance in London. I'm still on the fence about seeing that one. Might throw in the towel and see it the weekend before I move to London.
The idea is to work and to experiment. Some things will be creatively successful, some things will succeed at the box office, and some things will only - which is the biggest only - teach you things that see the future. And they're probably as valuable as any of your successes. -Harold Prince
