The story revolves around two couples living in the same block, both of which are struggling with their relationship. The plot uses classic farce techniques to amuse and keep the audience on their toes - you can't predict the twists any more than you would want to, and the endearing characters keep you intersted in their story and their needs. The music is varied and intelligently written: I'd be fascinated to hear it scored for more than just piano, but the arrangement for this production works fantastically in the space.The direction of the piece is tight and doesn't relent. The pace and humour keep the audience hooked to the story, and the minimalist set is one of the better ones I've seen at the festival. It is worth noting that aside from this, there is nothing 'fringe' about this production. It could stand up well in a mainstream theatre with some new lighting and a bigger set. The astounding thing about the show is the quality of the vocals on display. All four are excellent, and their credits, West End and otherwise, seem well deserved. In particular, Madalena Alberto's voice is stunning: she was the source of the moments that tingled the spine, and her characterisation was just as admirable. Mention must also go to the flawless and sensitive accompaniment throughout.I desired more of the lighting, with performers singing unlit on occasion, and some small dark patches in the space's rig. But the amazing voices and pace of the story mean that anyone watching doesn't linger on technicalities. The song 'Women Like You', brought the comic aspect to a head with great effect, while other numbers such as 'Easy to Say' really tug at your heart strings. On the whole this production looks ready to transfer and impress on a much bigger scale. I'll be keeping an eye out for a London transfer, and so should you.
