Somehow, the Grammys didn't discover disco until it had been around for nearly a decade. That's eight years after "Love Train" became the first disco track to top Billboard. That's three years after a disco version of the Star Wars cantina song was made. That's months after a riot of rockers chanting "Disco sucks!" left a pile of 12-inches on fire on Chicago's Comiskey Park. Gloria Gaynor won with "I Will Survive" but the Grammys, kowtowing to the haters, chopped this category as quickly as they wedged it in, thus ignoring dance music for almost two more decades out of fear that — what? Some bearded Pink Floyd fans might show up at their houses with picket signs?
