In 1955, at the peak of post-war American optimism, the number one song in the country was a bleak, percussive chant about being crushed by debt. "16 Tons," written by Merle Travis about the coal-mine company-store trap, sold millions to suburban listeners living the sunny American dream. The voice that made that paradox work belonged to Tennessee Ernie Ford, a classically trained singer who built a career playing a rural hillbilly.

This episode looks past the wholesome television smile to the more complicated man behind it: the craft and sophistication that turned a grim coal-country ballad into a crossover smash, the carefully managed public persona, and the private struggles that shadowed his later life. It is a portrait of image, artistry, and the costs that can hide behind fame.
