Mixing theatre with live indie-rock music on stage, the play looks at the friendships, fall-outs and the roller-coaster world of one of the UK's biggest bands – The Union. A dysfunctional group of musicians – The Union has four members: an Englishman, a Northern Irishman, a Scotsman and a Welshman.  But friendships and allegiances are tested when financial disaster strikes and Scottish guitarist Barry leaves the band. Artistic differences go head to head with alliances that run deep; can The Union survive? Hamish Pirie, associate director of The Traverse who previously directed Tim Price's Salt Root and Roe as part of the Donmar Warehouse's Trafalgar 2011 season, will direct. The show will also feature live music performed by the company, written by Gordon McIntyre.

Casting includes James Hillier as Damien the Englishman, Declan Rodgers as Aaron the Northern Irishman, Andy Clark as Barry the Scotsman and Matthew Bulgo as Gruff the Welshman.
