All the Surprise Appearances at Taylor Swift's Eras Tour So Far

Frequent Swift collaborator Aaron Dessner has surprised Swift's crowd at three Eras Tour concerts so far. At the 14 April show in Tampa, he joined Swift to perform "The Great War" during the surprise portion of the show. The song is a "3am" track from Swift's 2022 release "Midnights." The next day, he returned to perform "Mad Woman" with Swift. That song is from 2020's "Folklore." He returned again on 7 May in Nashville to perform "Would've, Could've, Should've," another "3am" track, with Swift in the pouring rain.

After performing "The Great War" with Swift, Dessner wrote on Instagram, "Playing the Great War for the first time in Tampa....Never in my wildest dreams did I imagine getting to play a song for 80,000 people on acoustic guitar with @taylorswift." He added heart and wide-eyed emojis and continued, "eternally grateful for all the music we have made and your friendship. The #tstheerastour is the greatest show I've ever seen!!!!!"

Dessner, who's part of the band The National, and Swift first collaborated on "Folklore" and they also cowrote songs on "Evermore" and the "3am" "Midnights" tracks.

Bridgers is one of the openers for the Eras Tour, and her first shows were Swift's Nashville stops on 5, 6, and 7 May. At the first of those shows, she and Swift surprised fans by adding their duet, "Nothing New," to the set list during the "Red" section. The song is one of the vault tracks off of 2021's "Red (Taylor's Version)." Bridgers came out to perform it with Swift at all three shows, so it seems the song will continue to have a place on the set list at the remaining stops where Bridgers is set to perform. Bridgers will open the other May tour dates in Pennsylvania, Massachusetts, and New Jersey.

Bridgers also surprised fans in her own way during her first two sets in Nashville (she did not open at the third show due to rain). At both shows, she brought out her supergroup Boygenius. The band, made up of her, Lucy Dacus, and Julien Baker, just released their first full-length album in March.
