Carly Simon's memoir finally has a pub date. Simon's book, called "Boys in the Trees," will be in stores Tuesday. The publisher, Flatiron Press, is promising a vivid account of the singer's life, beginning in childhood — her father was Richard L. Simon, cofounder of publishing giant Simon & Schuster — followed by her debut as a folk singer with sister Lucy and, finally, Simon's enormously successful solo career, which yielded 13 Top 40 hits, including "You're So Vain." (Whether she writes about the inspiration for the song, we shall see. But we do know Simon goes on at length about her ex, singer James Taylor.) Fans of her music will be pleased to know that the book comes with two CDs. The 31 songs include two previously unreleased tracks — one recorded during the sessions for Simon's 1978 album "Boys in the Trees," and a new one, "I Can't Thank You Enough," written with her son Ben Taylor. That song is already posted on YouTube.
