Im beginning to think that Musical Theatre @ George Square are like some dodgy wartime butcher, whos keeping all the good stuff round the back. With a wink and a flash of your ankle, George will wrap up a couple of extra sausages for you and lead you to the hut that is a whole street away from the main theatre, tucked behind a terraced row of town houses. This portion of prime pork is Conor Mitchells excellent 90-minute therapy session, Have A Nice Life.Im a fan of Mitchells work, and this piece in particular. It the sort of musical youd expect if Sondheim had written I Love You, Your Perfect, Now Change. He uses dissonant chords and melodies that are tricky to sing with bitingly funny lyrics and one-liners that any comic currently up at the Assembly Rooms would be proud of. It deals with the lives of seven characters in a real-time psychotherapy session. Their leader, Patrick, attempts to keep the group on track as his various charges take their turn to reveal their own particular quirk. It is the arrival of a new member that ultimately causes this to be the last session for them all.Bill Feltys direction is tight, dealing with the challenge of potentially staring at an arc of chairs well by squeezing the most out of the George 2 space. Its punctuated with some very funny set dance pieces choreographed by Nancy Berman Kantra that could have come from a Busby Berkeley spoof. After a slightly uneven start, the cast find their energy and in particular Amy Acchione, as über-clingy Jackie, brings a natural comic performance to her role which makes her stand out for special mention. This is one of those perfect choices for a Fringe musical quirky, risk-taking and not taking itself too seriously. Definitely worth a look.
