Overview: The format of Elvis' fantastic interview/performance show changes yet again as a major, magical musical surprise is pulled from Elvis' hat. And by pulled, I mean as in a "guitar pull". Legend has it that the late, great Johnny Cash would have musicians and writers pile into his Tennessee living room and take turns playing their songs - luminaries such as Kris Kristofferson, Joni Mitchell and Bob Dylan. The musical gatherings were referred to as a "guitar pull". Now, Cash's daughter, Rosanne, joins with long-time family friend Kris Kristofferson and a new group of legendary singer-songwriters for an hour of old and new classics and a lively discussion on the art of songwriting. Norah Jones, the silken voiced daughter of Ravi Shankar, even reveals a new 'old classic' co-written by Hank Williams himself; while the Sundance web site reports that John Mellencamp "strips his music (old and new) down to the bare essentials"
