MONTREAL – There was a universally catholic intensity to Leonard Cohen’s work. It was found in his “Song of Bernadette,” which Jennifer Warnes recorded, in his song “Suzanne” when he referenced Montreal’s Notre-Dame-de-Bonsecours Chapel (“the sun shines down like honey on our Lady of the Harbour”), in his novel Beautiful Losers about St. Kateri Tekakwitha, and in his astonishing spiritual, Book of Mercy.
