Opry Video Classics: Pioneers.

The Carter Family, Roy Acuff and the Sons of the Pioneers belong to a select group of the earliest and most successful country recording artists. Pioneers spotlights them all doing such signature songs as Keep On the Sunny Side, Wabash Cannonball and Tumbling Tumbleweeds, alongside the influential blue-grass bands of Bill Monroe and Flatt & Scruggs. And when Grandpa Jones stomps through Good Old Mountain Dew, you won't be able to sit down.
