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 April 14 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 May 7 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!!!!!"

On June 18, Dessner joined Swift to perform "Seven," another "Folklore" song. And at night two in Cincinnati (Dessner's hometown) on July 1, he played guitar during Swift's performance of the "Evermore" track "Ivy."

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 May 5, 6, and 7. 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)." The song was added to the set list for all of Swift's May shows, so fans in Pennsylvania, Massachusetts, and New Jersey were treated to the duet.

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.

On May 26 — Swift's first night in East Rutherford, NJ — she brought out New Jersey native (and frequent collaborator) Jack Antonoff. The pair performed "Getaway Car" off of 2017's "Reputation," together. The song is a fan favorite in part because Swift and Antonoff's writing process was captured in the 2020 documentary "Miss Americana." In the clip, the pair jump over each other to write the words to the song's bridge in a sudden burst of inspiration.

On the morning of May 26, Swift released "Karma (Remix)" featuring Ice Spice. During her concert that night, Swift debuted the music video, which also features the rapper. And then, when she ended the show with "Karma," Ice Spice came out to perform their version with Swift and her dancers. But that was just the beginning. The Bronx native ended up joining Swift at all three New Jersey shows that weekend.

On June 3, Swift brought Morris out in Chicago to perform their duet "You All Over Me" together live for the first time. The song was a vault track on 2021's "Fearless (Taylor's Version)." Swift called Morris one of her "favorite artists" before they sang the duet, during which they both played guitar.

Morris wrote on TikTok alongside a video of their performance, "Thank you so much for having me @Taylor Swift. Your generosity to me in these last 7 years is insurmountable and I love you so." She added on Instagram, "We finally got to play 'You All Over Me' and I won't ever be shutting up about it."
