Lightning strikes every time Taylor Swift moves.
And her June 14 show in Liverpool, England, was especially electric with the Eras Tour debut of 2016's "This Is What You Came For" by Rihanna and Calvin Harris, who Taylor was dating at the time she co-wrote the dance hit.
As seen in concert footage circulating on social media, the "Karma" singer told the crowd, "Every single time I have an acoustic set, I'm always trying to think of things you might want to hear—maybe things that might be a little bit unexpected."
Taylor added, "Let's see how we did tonight."
Needless to say, the audience went wild, erupting in cheers before joining her in song.
The 34-year-old has only performed the track twice since its release. She played a piano version of the song in October 2016—six months after its debut—at the Formula 1 U.S. Grand Prix in Austin, Texas. Nearly four months later, the Grammy winner performed it on an acoustic guitar during a Super Saturday Night concert in Houston.
Initially, Taylor received songwriting credit for the single under the pseudonym Nils Sjöberg. But after she and Calvin, 40, broke up in June 2016 following almost a year-and-a-half of dating, E! News confirmed that the "Cruel Summer" artist was one of the masterminds behind the chart-topping track.
"I wrote under the name Nils Sjöberg because those are two of the most popular names of Swedish males," Taylor later explained of the alias in a 2020 Rolling Stone interview. "And nobody knew for a while. I remembered always hearing that when Prince wrote 'Manic Monday,' they didn't reveal it for a couple of months."
And Taylor kept the surprises going at her Eras Tour show in Liverpool, mashing up "This Is What You Came For" with her 2020 evermore track "Gold Rush." As part of the set, she also changed the lyrics to her 2022 Midnights tune "The Great War," replacing "we" and "I" when she sang, "I vowed not to cry anymore if we survived the great war."
But these concert moments are on numbered days. After all, Taylor recently announced that she'll be ending the her sold-out tour in December.
