MONTREAL — In an octagonal chamber at the Musée d’Art Contemporain de Montréal, a spectator in a trance-like state hums Leonard Cohen’s “Hallelujah” as numbers on a digital display leap up to 631. That’s how many people on Earth are streaming Cohen’s version of the secular anthem right now, each represented by a recorded voice humming the song.

In a nearby neighborhood is Bar Suzanne, a new speakeasy named after one of Cohen’s most celebrated muses and songs. The lyrics “takes you down” are written in bold black letters on the stairs — a playful allusion to the song. Olivier Farley, the owner, said he chose the name because “Everyone in Montreal is proud of Leonard Cohen — the French, the English; he is sacred here.”

Then there is the imposing, luridly colorful mural that stretches nine full stories down the side of a building in the Plateau-Mont-Royal neighborhood. Pilgrims come daily to pay homage to the painted portrait of Cohen, staring plaintively from under his signature fedora. A second, even more towering Cohen-inspired mural, can be found in the heart of downtown.

Montreal has a real case of Leonard Cohen mania. More than a year after this poet, novelist and singer-songwriter died at the age of 82, he has become something of an urban prophet here. A new generation is memorizing his lyrics. There is the museum exhibition, “Leonard Cohen: A Crack in Everything,” inspired by his life and work. And Cohen-obsessed residents are making trips to Moishes, a storied steakhouse, to sample his favorite lamb chops.
