Paul McCartney heard skiffle on the radio as a Liverpool teenager and it changed his life. Seven decades later he used artificial intelligence to extract John Lennon’s voice from a degraded cassette tape and finish a Beatles song. No other career in popular music spans as much ground or adapts as relentlessly.

This episode follows McCartney from his mother’s death and his partnership with Lennon through Wings, his solo decades, and his late-career willingness to embrace technology that would have been unimaginable when he first picked up a guitar.
