'Jimmy Fallon' Producer Explains the Emotional Reason for Taylor Swift's Unplanned 'New Year's Day' Performance

The meaning behind Taylor Swift‘s unplanned Tonight Show Starring Jimmy Fallon performance was even more emotional than the song itself.

Show writer and producer Mike DiCenzo? told the heartbreaking story of her performance of Reputation track “New Year’s Day” – and the shocking accidental lyrical connection to Jimmy and his mom – in a series of tweets that night.

“First, a quick word about Taylor Swift. She was not scheduled to do our show today. But we wanted something special for this first show back, so we asked her on a complete whim, since she had been in town doing SNL. She said yes with zero hesitation,” he wrote on Twitter.

“She sang ‘New Year’s Day.’ No one had heard it. Suddenly she sings the line, ‘Squeeze my hand 3 times in the back of the taxi.’ I nearly gasped. Tears. I think everyone in the audience started sobbing. I could see Jimmy silhouetted at his desk dabbing his eyes with a tissue. We all lost it. It was a beautiful coincidence in a beautiful performance. ‘Hold on to your memories, they will hold on to you,’ Taylor sang.”

“That hug between Jimmy and Taylor after the song was 100% real emotion. Whatever you think of Taylor, she did something beautiful for Jimmy and our show today, and we’re forever grateful.”
