Marv, Lonnie and I sit with Nashville HOF songwriter, author and man who worked with a Beatle about his lifelong love of the Fabs, touring (and writing!) with Carole King, his Brian Epstein-themed song on the new Billy J. Kramer record, collaborating (and recording) with Ringo and the forthcoming Ringo country album.     We also dig into his new novel ("Reunion"), which imagines a universe where John Lennon's fate changed, and all four were still present when Paul (at the urging of his daughters) decides to approach the others, as "the right four people" is one of the ways he might be able to overcome his heartache.
