Rather looking forward to it, having been thinking whenever I've been in London and seen the posters for it that it looks interesting, and then noticed recently that Rory Pond-Williams himself, Mr Arthur Darvill, is in it for a limited period.
Should be an entertaining afternoon (we're going for the matinee, on the basis that it should be less busy than the evenings. Although there weren't many seats left when I booked just now…).
Probably ought to check out the film it's based on at some point. A romantic musical sounds, frankly, right up my street.
