In the latest installment of our Motley Fool Conversations podcast, I spoke with Harry Shearer, author-satirist-actor-entrepreneur and the man behind the voices of over 20 characters on The Simpsons. Shearer is currently in London promoting Unwigged & Unplugged and his new parody song, "Little GM." Among the questions he pondered:

  • Is the legendary rock band Spinal Tap recession-proof?
  • Does Google's (NASDAQ:GOOG) YouTube make it easier or harder to be an entertainer these days?
  • How does America's economy look from a U.K. perspective?
  • What does Simpsons corporate titan Montgomery Burns think about shareholders having a say on executive compensation?
