These days, country and pop acts regularly invade each other’s territory. But in Nashville during the 1970s, “crossover” was a dirty word. Then came two rising stars who offered up a new hybrid of Americana-style pop.

John Denver infused his folk balladry with homespun lyrics about country roads and wide-open skies. Olivia Newton-John sang over twangy melodies that belied her British-Australian roots. Both faced backlash—especially when they started topping the country and pop charts simultaneously and winning prizes that used to go to Nashville legends.

Eventually, both artists outgrew country music. Denver became a ubiquitous entertainer and beloved Muppet wingman. Newton-John dazzled in the film Grease, then reinvented herself as a leather-clad siren unafraid to get physical.
