Taylor Swift agreed to perform on The Tonight Show and pay subtle tribute to Jimmy Fallon's mom “on a complete whim”

TIME

Her performance of "New Year’s Day," with a line echoing something Fallon had said in paying tribute to his mom, was “a beautiful coincidence in a beautiful performance,” tweeted Tonight Show writer/producer Mike DiCenzo, who adds that Swift was asked by the staff at the last minute since she had just performed in nearby on SNL. “I could see Jimmy silhouetted at his desk dabbing his eyes with a tissue. We all lost it,” DiCenzo adds. ALSO: Carson Daly’s mom and Fallon’s mom were close friends.
