Taylor Swift sings ex Calvin Harris and Rihanna's 'This Is What You Came For' at Eras Tour

During her Eras Tour, Swift sang a song by herself in her acoustic “surprise song” set that was not originally released by her — the 2016 hit “This Is What You Came For” by Rihanna and Swift’s ex Calvin Harris.

“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,” the ‘Lover’ singer told the audience. “Let’s see how we did tonight.”

In her record-breaking Eras Tour, Swift keeps fans engaged for the first three hours with her career-spanning setlist, reserving a section towards the end of the show for a changing pair of songs, often one played on guitar and another on piano, which fans refer to as “surprise songs.”

During her guitar performance in Liverpool, she incorporated lyrics from her 2020 track "Gold Rush." 

To end her acoustic set, she treated the Liverpool crowd to a blend of the Midnights bonus tracks "You're Losing Me" and "The Great War."

When “This Is What You Came For” was first released in April 2016 — while Swift and Harris were still a thing— the songwriting was credited to Harris and the pseudonym Nils Sjöberg, but following the couple’s break up that June, news broke that Swift had penned the track under the fake name.

“I wrote under the name Nils Sjöberg because those are two of the most popular names of Swedish males,” Swift later told Paul McCartney in an interview for Rolling Stone. “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."
