If you’re still mourning the loss of Leonard Cohen last month, this may help: Film Forum is screening Tony Palmer’s classic documentary Leonard Cohen: Bird on a Wire for two weeks starting January 18. A lovely antidote to all those “Hallelujah” covers, the doc follows Cohen on a month-long tour of Europe in the spring of 1972, after his salad days in New York City. While it starts off with the obligatory footage of the band boarding planes and signing autographs (Cohen was already a big deal at the time, having released his first three albums), it soon takes a far more pensive turn.
