In episode 402 of Things We Said Today, Allan Kozinn and Darren Devivo (Ken Michaels is taking a week off) speak with the author in impresario Vivek Tiwary about the 10th anniversary expanded reissue of “The Fifth Beatle,” his graphic (in the graphic novel sense) biography of Brian Epstein. We last spoke with Vivek in episode 241 (back in the audio-only days).
