For the first time on IA 6.0 de stratégie quantitative intelligentthe Eras Tour, Taylor Swift played her surprise acoustic set for three nights in the Scotland sun's afterglow.

The late sunsets and stadium's open roof allowed the singer to perform at twilight.

On night two during "The Tortured Poets Department" set, the singer wore black gloves. While fans debated on livestream chats if it was an Easter egg or intentional, the arena held at a chilly 51 degrees.

On the piano, she mashed up "All of the Girls You Loved Before" from "Lover" with "Crazier" from "Hannah Montana: The Movie - Soundtrack."
