The pop star wasn't scheduled to perform, but made a decision to give a heartfelt rendition of the Reputation tune in honor of Fallon's mother.
Taylor Swift gave fans a huge surprise this evening - she performed one of her brand new songs on The Tonight Show! Seated at a piano, Swift demanded attention with the introspective and emotional tune.
Our thoughts go out to Jimmy during this tough time for him, and in general the past couple of months have caused his to reevaluate our position on the Fallon iteration of The Tonight Show in general. Mike DiCenzo, a writer/producer on The Tonight Show, shared his thoughts on the show and performance.
He finished by promising his mother: "Mum, I'll never stop trying to make you laugh". While she was in the hospital, Fallon said he held his dying mother's hand and did the same thing she used to do when he was young: He squeezed her hand three times before telling her he loved her. "I just knew we were in trouble, you know?"
"Suddenly she sings the line, 'Squeeze my hand three times in the back of the taxi, '" he continued.
Gloria's advice? "Wash your hands after being near that Paris Hilton", she joked on the show.
"She also stole everything!" said Daly with a laugh.
She was 68 years old.
"I could see Jimmy silhouetted at his desk dabbing his eyes with a tissue". It was a handsome coincidence in a lovely performance. 'Some of you know my mother, Gloria, passed away recently, and I canceled our shows last week to be with my family and make arrangements'.
Struggling to control his emotions, he told the audience: Thank you for watching, thank you for helping me and my family recover from this loss.
