In 2016, we learned Patrick Leonard reveals that Leonard Cohen was working on an R&B record by Tom Power (CBC: November 11, 2016). Hear the Patrick Leonard interview at the link.
I wasn’t with Leonard when he died, but I’m certain that until he couldn’t hold a pen in his hand, he was working. That’s the way Leonard was. He had been weak and ill for a while, but he was working all the time. The hours in a day that he could work were narrowing, but the determination was still there. I think it was clear that the end was in sight, but I don’t think his October  release You Want It Darker is him leaning toward mortality: Go back and listen to his first album [1967’s Songs of Leonard Cohen]—there are mortality issues there. The songs we were working on before he died were really light R&B, beautiful Leonard Cohen love songs. Another project we were working on was an extension of You Want It Darker’s reprise of ‘Treaty.’ We had 10 arrangements written and half of them recorded already—beautiful melodic arrangements—without his voice on them. Maybe they will see the light of day. I don’t know.
Today, we have this:
Honored and humbled to be asked by Adam Cohen to perform piano on the last recordings of his father Leonard Cohen. Rare moments of beauty, may they see the light soon for your ears. #PeopleFestival pic.twitter.com/QYg9RkmVBK
