Former Canadian Prime Minister Pierre Elliott Trudeau was an operatic figure with a very big life. And now there’s to be an opera about him. “Trudeau: Long March/Shining Path is being written by librettist George Elliott Clarke and jazz composer D.D. Jackson. Clarke, a poet acclaimed for his Whylah Falls and author of the novel George and Rue, has written two earlier operas: Beatrice Chancy, about slaves in Nova Scotia, and Québécité, which is the story of interracial lovers.”
