If you ever want to make yourself really sad, listen to Joni Mitchell’s cover of “Why Do Fools Fall in Love” (awful), then Diana Ross’s (worse), then James Taylor’s version of “Up on a Roof” (deadly dull), then Bruce Willis’s take on “Under the Boardwalk” (at which point, you might want to shoot yourself). Then play the originals, get happy again, and wonder why anyone ever tries to mess with perfection.
