Synopsis: A host of popular artists -- including Beth Orton, Nick Cave, Rufus Wainright and the U2 boys -- come together for a memorable evening of music at the Sydney Opera House, paying tribute to legendary songwriter Leonard Cohen. Producing a piece that's part concert film and part documentary, filmmaker Lian Lunson combines footage from the show with archival material and intimate interviews, resulting in a fascinating portrait of a gifted tunesmith.
