After all, you've already come to London a couple of times, and as Samuel Jonson said, it's easier to be tired of life than tired of London.
In fact, Steemfest should come to London, surely, after our US cousins have a turn (only fair).
So yes, if you come London way, let me know. :)
Nb: The show was great. I'm a big fan of the Christian Slater eighties movie, and the musical gets right just about everything that was great about the film.
