What does it sound like when Leonard Cohen fans of 50+ years sing I'm Your Man?

It was a quest to find the most die-hard of Leonard Cohen fans.

The pre-requisite? Have at least 50 years of loving Cohen's music under your belt.

The opportunity? You get to pay tribute to the music legend, who died last November, by performing and recording your own version of his 1988 hit I'm Your Man.

"I was a Leonard Cohen fan from the time I was 17," says one of the 18 people chosen to take part in the project called I'm Your Man (A Portrait of Leonard Cohen).

"I'm at the point of my life where there aren't that many once-in-a-lifetime experiences left, aside from death."

The recording sessions, which were shot at the Phi Centre in Montreal, have been turned into a 19-channel video installation by artist Candice Breitz.

The recordings also include the back-up vocals of the Shaar Hashomayim Synagogue Choir, an all-male choir representing the Westmount congregation that Cohen belonged to all his life. The choir also sang on Cohen's final album.
