A little-remembered Michigan garage band, Terry Knight & the Pack touched the charts with their remake of ‘I (Who Have Nothing)’ and were mainstays of syndicated teen dance party show Upbeat. Their self-titled debut album and “Reflections” contain grungy originals and covers, but the band’s real breakthrough came a few years later when, with Knight producing and masterminding behind-the-scenes, they morphed into hard rock superstars Grand Funk Railroad.
