The cast of the London production of Les Misérables have sung Christmas carols outdoors to raise money for Great Ormond Street Hospital for children. The stars sang around the corner from the Sondheim Theatre where Les Misérables plays. The world’s longest-running musical, Les Misérables, recently celebrated its 40th anniversary in London. #merrychristmas #christmas #lesmiserables #carols #greatormondstreet
