Watch Taylor Swift bring back Lover’s The Archer or the Eras tour surprise song in Amsterdam

Performing to a packed audience in Amsterdam, Taylor Swift's unexpected Fourth of July performance featured "The Archer," a song that hadn't been included in the Paris setlist.

 She sang "Combat," and the crowd at the Johan Cruijff Arena erupted with cheers."I'm ready for combat,” she declared.

During the Eras Tour, Swift concluded the "Lover" era with "The Archer," vanishing into the stage. In April, she streamlined her set list to include more "Tortured Poets" songs, ultimately ending the "Lover" era with its title track.

During the piano segment of her acoustic set, Swift sang, "can I ask you a question?” blending the "Midnights" track "Question...?" with "The Archer."

Prior to her two-song piano performance, Swift slung her guitar over her shoulder.

"I really wanted to challenge myself to play as many songs from different eras and albums," she mentioned in her bright orange dress. "We'll see how this one goes."

Swift merged "Guilty as Sin?" from "The Tortured Poets Department" with "Untouchable" from "Fearless (Taylor's Version)."

"You guys sang that so loud," she remarked, sounding impressed.  "It's just the most thrilling feeling when I can hear your voices so loud, over even what's coming out of the speakers."

The Eras Tour star has two more nights left in Amsterdam before heading to Zurich.
