Oct 23, 2016 8:34 PM CUT [Taylor Swift](http://motto.time.com/4540332/taylor-swift-seal-photographs-groping-lawsuit/ "undefined") threw a curveball at the audience at Circuit of the Americas race track on Saturday night by performing her [ex-boyfriend Calvin Harris’](http://time.com/4482852/calvin-harris-on-how-all-hell-broke-loose-after-he-and-taylor-swift-broke-up/ "undefined") song “This Is What You Came For.” Sitting at a piano, Swift played and sang the tune that she co-wrote under a pseudonym for the crowd. “I’ve never played this song live before,” she said. “But if you know it, maybe you could sing along, and then I could get to know what that feels like to hear it sung back to me.” The hit song made waves over the summer after Harris tweeted that Swift, who had wanted to keep her identity and involvement under wraps, [wrote the lyrics](http://people.com/celebrity/taylor-swift-wrote-ex-calvin-harris-this-is-what-you-came-for/ "undefined") to the song with Rihanna. She is credited with the pseudonym Nils Sjoberg. > [](https://twitter.com/tayIorscurIs/status/790013426407870465) ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4542014/taylor-swift-calvin-harris-concert/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4542014/taylor-swift-calvin-harris-concert/"},"headline":"Taylor Swift Performs Ex Calvin Harris' 'This Is What You Came For' at Concert","datePublished":"2016-10-23T20:34:46.000Z","dateModified":"2026-04-13T07:37:54.169Z","description":"\"I've never played this song live before\"","url":"https://time.com/4542014/taylor-swift-calvin-harris-concert/","keywords":["Newsfeed","Music"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt10a718cf27fce187/6988ab2ccd1bba3373702cd8/taylor-swift.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Mahita Gajanan","jobTitle":"Gajanan is an editor at TIME.","url":"https://time.com/author/mahita-gajanan/"}],"articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt10a718cf27fce187/6988ab2ccd1bba3373702cd8/taylor-swift.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Taylor Swift F1 USGP Austin, Texas","caption":"AUSTIN, TX - OCTOBER 22: Singer/songwiter Taylor Swift perfoms onstage during the Formula 1 USGP on October 22, 2016 in Austin, Texas.
