In the video Leonard Cohen: Tower of Song - A Memorial Tribute Documentary by Jack Bender available on Vimeo, there's a montage starting around 1:20:00.
Parts of the lyrics:
My heart will be hers for less than a second
Our lives will collide
And she will be born to someone like you
And that is the longing
I can't figure out the title of this song on Spotify, and all google searches on any of the phrases heard only point to collections of poems like The Book of Longing. Does anyone know the title of this song? Maybe it's not even recorded as a song, but only part of a live performance?
Thank you for any suggestions!
