Inexplicably left out of the movie

Fans of Leonard Cohen should check out "I'm Your Man," the tribute concert/documentary screening in theatres now. While the production values are subpar, the performances are decent and Cohen is candid and chatty during the extended discussion sections. Anyhow, the great Martha Wainwright performs "The Traitor" in the film (she also sings a verse of "Hallelujah"); she did my favourite Cohen song, "Tower of Song," on Letterman to promote the film and the upcoming record. The movie ends with U2 (ugh) backing Cohen on "Tower," which explais why Martha's (better) version was left out. Anyhow, enjoy.
