Please contribute as you are able...videos or sound clips in which you can hear the fighters speak are especially welcomed. I'll start it off with two clips: first, this interview with Jack Dempsey and Rocky Marciano. It's the only video of Dempsey speaking that I've seen so far. And second, a sparring session between an aging Jack Johnson and Joe Jeannette. You can hear Johnson address the crowd in his unique and peculiar voice.
