Satirist Harry Shearer voices several characters on The Simpsons; he’s the bassist for Spinal Tap, host of Le Show on public radio and an impersonator extraordinaire. Working with historian Stanley Kutler, he’s become a student of President Richard Nixon’s White House tapes. Now he’s done a series for television, dramatizing the taped conversations word for word. Nixon’s the One debuted on TV in Britain, and is now running on YouTube.
