The Last Waltz. Not sure how I missed this one over the years, but a good watch. Great cameos by several important artists. Having followed Emmylou Harris over the years, I'd forgotten how sexy she was in her youth. I liked her voice better then, too. A little less brittle.
Go back and look for the cocaine booger in Neil Young's nose. Scorsese, in post production, actually tried a form of traveling matte to hide it, but it's clearly there.
