It's no surprise Taylor Swift has been playing two additional songs during each night her tour. But Cincinnati fans got a little extra on night two at Paycor Stadium.The second night of Swift's "Eras" tour began in hectic fashion, with Swift performing an hour earlier than originally planned. Most 'Swifties' had anticipated two additional songs, as she's been doing every stop, but they never thought she would play three.Swift started Saturday night's surprise set list with "Ivy," which features Cincinnati native and "The National" musician Aaron Dessner. Dessner joined Swift on stage for the song, which had never been performed live before Saturday night.While her surprise songs are usually ones she wrote, Swift called up opening act Gracie Abrams to perform Abrams' song, "I Miss You, I'm Sorry." This marked the first song Swift has performed that is not her own.She ended the surprise song set with "Call It What You Want" on the piano.
