Chilling video captured a "human cannonball" stunt gone wrong at a California fair. | USA TODAY Video

On the first night at the brand-new Opry House: "They projected a film, of Roy Acuff singing “The Wabash Cannonball” from back in the 40s and they’re showing this on the screen in the new Opry House. And all of a sudden, that screen begins to lift and there’s Roy Acuff singing the same song. It never missed a beat. It was from the old film in the 40s to here’s Roy Acuff now in his 70s still singing “The Wabash Cannonball.” I stood there and cried." - Bill Anderson on Ken Burns: Country Music PBS
