John Lennon Tribute Week kicks off with author Ken Sharp, who has just penned “Starting Over: The Making of John Lennon and Yoko Ono’s Double Fantasy” (MTV books).  Sharp talks with a wide array of people who were involved with Lennon’s comeback album, including Yoko Ono, David Geffen, the session musicians, the producer, engineer and photographer.  All of them paint an interesting picture of what would end up being the singer’s final studio album released during his lifetime.  We also talk to Sharp about his own infectious music.
