The Best Day (Taylor’s Version)

This song is a love letter to Taylor Swift's mother, Andrea Swift, who usually accompanies her daughter while she's on tour.

The country star told CMT Radio the story of this song, which she wrote out on the road and kept as a secret from her mom until Christmas. Swift explained: "In the first verse, I was talking about being 5 years old, so as a writer, it was really fun to go back to that place of the way that I used to talk when I was 5. I wrote the song from that perspective, and I starting thinking, 'What would I be thinking if I was 5 and I was remembering this?' And it goes, 'I'm 5 years old/It's getting cold and I've got my big coat on.' It had language like that - that makes me really think back to that time. I actually wrote that song without telling my mom and recorded it without telling my mom. Complete secret session. Then I got the track back and synced up all these home videos of me when I was a little kid and made this video and played it for my mom on Christmas and said, 'Merry Christmas!' She had no idea that it was me singing for the first half of the song. And then she just broke down crying when she realized I had done this whole thing to surprise her. It was a really cool moment."

Taylor had to drop this touching song from her Fearless tour set list as her mother burst into tears backstage every time she heard it. Andrea explained, "She had to drop it from the set because I kept breaking down."
