I was the only kid at Hiller Elementary who saved up his birthday money to buy Carly Simon records at Korvettes, but even I can admit that her singles tended to considerably better than most of her album material. There were exceptions, of course, and none more so than "Libby," the epic ballad written for her friend Libby Titus -- the singer, songwriter, actress and concert producer -- that isn't all love and admiration. Simon's lyrics have never been more controlled and poignant than on "Libby," and its breathless captured-in-one-take effect sweeps you into the story like few.songs ever have.
