Sorry to hear he's gone. Strange to think that he was 33 when he released his first studio album.
I bought his 1967 debut The Songs of Leonard Cohen (favourite track was Suzanne) and we played it endlessly at parties during the late hours, once the mood had softened. I have lovely memories of those times.
I went on to buy his next two albums, Songs from a Room (1969) and Songs of Love and Hate (1971), but I stopped then as I didn't want him to change, the moment was perfect right there.
His most covered song, Hallelujah, is my least favourite of all (I'm an atheist, so all that religious stuff left me cold) but I know a lot of people think of that track first when they hear his name.
RIP Leonard, you've left us with some beautiful material to revisit time and again.
