It's hard to believe that it's been a year since Leonard Cohen left this mortal coil, but his life is currently being celebrated in his native Montreal.

There is an art exhibition called ' Leonard Cohen – Une brèche en toute chose / A Crack in Everything' running in his memory at the city's Museum of Contemporary Art, and on Monday night a concert dubbed 'Tower of Song: A Memorial Tribute to Leonard Cohen' was held at the Bell Center.

It featured everyone from Philip Glass to Sting, Feist, Elvis Costello, Damien Rice, k.d. lang, Courtney Love, Seth Rogen and more - but one of the highlights was reportedly a duet between Lana Del Rey and Cohen's musician son, Adam.

They sang 'Chelsea Hotel No. 2' together, which you can see below:
