By 1964, when the US population stood at nearly 192 million, four out of every 10 Americans were under 20 years old. More people were 17 than any other age.

“If anyone asks you what kind of music you play, tell him ‘pop.’ Buddy Holly warned a fellow musician. “Don’t tell him ‘rock ‘n’ roll’ or they won’t even let you in the hotel."

Whether shake, shake, shaking your booty in satin hot pants or physically spelling out YMCA in a double-knit polyester leisure suit, Americans in the 1970s feverishly danced away countless Saturday nights under a dazzling mirrored ball. A veritable disco inferno.
