Stoneman Family: Surf Bluegrass Instru.

"Here's a Bluegrass-Hullabaloo crossover performance: Donna Stoneman of the Stoneman Family shredding it on her electric mandolin to Bill Monroe's Bluegrass Stomp while her sister Ronnie yelps, gyrates and beats her tambourine, from an unknown 1960's TV show. The lecherous gentleman wandering into the recording session is none other than Spike Jones sideman Doodles Weaver. This clip may be from the Marty Robbins movie Road To Nashville."
