Happy 76th Birthday to Sir Paul McCartney!      A very special episode as we continue our visit with Darin Murphy.    This week, he gets behind the kit and spends an hour demonstrating and discussing the finer points of Ringo's drumming technique.    Along the way we discuss why Ringo was not just perfect for the band, but essential to Beatlemania and beyond.       Other topics include Pete Best and the "atom beat," the versatility of Ringo's snare, cymbals and hi-hat (open/half-open/closed), and finally "the quickest right hand in the West."
