For the first time, Art Garfunkel shares the stage at Carnegie Hall with his family - his wife, Kathryn Luce and their two sons, Arthur Jr., 27 and Beau Daniel, 13. The concert will include solos, duets and numbers by the entire family. Songs will range from such crowd favorites as "Devoted to You" to "Canal," "Smile," "The Boxer" and "Scarborough Fair." In addition, there will be a reading of musings from Art Garfunkel's memoir, "What Is It All But Luminous" (Knopf).
