We’ve all got a ‘Hallelujah’ story. For this writer, Leonard Cohen’s most famous song represents the fragile beauty of musical bonding. An ex-fiancee first played me Jeff Buckley’s version on one of many long nights sitting up digging through our old CDs to sing along to, and it seemed to me to encapsulate the quasi-religious power of the secret chords we’d share with each other, the intrinsic marriage of music, trust, love and unspoken connection. When we broke up, I couldn’t listen to it for years. And so sitting through Dan Geller and Dayna Goldfine’s moving exploration of the man and the song, Hallelujah: Leonard Cohen, A Journey, A Song, was something of a trial.
