Information for Ben and Imo at Orange Tree Theatre, Outer London (Play). The 1953 Coronation of Queen Elizabeth II is fast approaching. To mark the occasion, Benjamin Britten has just nine months to write a new opera about her predecessor Elizabeth I. Into the world of the disheartened composer enters the exuberant and passionate Imogen Holst, daughter of Gustav and an accomplished musician in her own right. Her candid and can-do attitude proves to be the perfect foil for the capricious and often maddening Britten, and what begins as an arrangement of practical support turns into a bond that not only sees Gloriana to its premiere but endures throughout the rest of their lives.
