“Shindig!” might have been forgotten were it not for Artie Ripp who, 20 years later, became obsessed with resurrecting “some old footage collecting dust, which also happened to be some of the most historically important performances by rock pioneers.” Artie spent five years coaxing ABC to unearth “Shindig!” The resulting home-video series offers half-hour compilations of the show’s best moments. VH-1 music network broadcast a “Shindig!” day with prizes and clips from the videotapes.
