Taylor Swift rarely grants journalists access to her life. But when she was just 21 years old, she invited 60 Minutes inside her home and on tour to see firsthand how she was revolutionizing the music business. Now, for the first time, we hear previously unreleased audio. While Lesley Stahl and a 60 Minutes team spent long days with Swift in both Nashville and Los Angeles, only thirteen minutes was broadcast on television. As we take a "second look," these conversations help us better understand Swift's unbelievable career trajectory. You'll also hear fascinating recollections from correspondent Lesley Stahl and producer Shari Finkelstein about what it was like to spend time with an artist as she was still finding her voice.
