It’s a moment that could only be pulled off by the legendary crooner himself, Frank Sinatra. September 5, 1976, two of Hollywood’s original Kings of Comedy, Dean Martin and Jerry Lewis, were brought together again after a 20 year feud. Lewis and Martin made millions laugh in the 1950s as their comedy duo cut up on radio and television. The two had a falling out, and weren’t reunited until they were brought together 40 years ago. We take you inside this monumental reunion with Jerry Lewis and Dean Martin’s daughter, Deena. See how the moment came together and the effect it had on viewers who had the chance to watch it live.
