It's one of the most performed New Zealand productions - 200 shows over 5 years here and overseas. Robert Lord's family epic Joyful and Triumphant spans 4 decades of the Bishop family's Christmas Days. Robert died just before rehearsals started. Now, almost 20 years since the last show, it's returning to the stage - with many of the original actors who are now playing 'older' roles. Lynn Freeman talks to three of them - Catherine Downes, Jane Waddell and Michele Amas.
