Taylor Swift surprised fans in London at Wembley Stadium on Saturday with a performance of “I Did Something Bad,” it was her first time playing the Reputation song during her Eras Tour run.

As fan-captured video showcased, to introduce it, she told the crowd she’s “done hundreds of songs” on this tour, but “I’ve not done one of my favorite ones ‘cause I’ve been waiting for the right crowd.” She added that she’s seen “Tony Award-winning performances in this crowd”  and pointed out that it’s “such a dream to perform for a crowd like this,” particularly with 92,000 people who are into it: “It’s magic,” she said, before launching into the song on acoustic guitar.

Fans have been hoping she might announce the re-recorded version of Reputation (Taylor’s Version), and the taste from the original 2017 album have some hoping she might announce it before her final Wembley show on Aug. 20.

She followed up the Reputation gem with a mashup of The Tortured Poets Department’s “My Boy Only Breaks His Favorite Toys” and Evermore’s “Coney Island” on piano.

On Friday, she debuted Lover track “London Boy” during the second night of her five-night stand in London. During her first Wembley show Thursday, she brought out Ed Sheeran to play “Everything Has Changed” and “Thinking Out Loud.”

Earlier this month, Swift was slated to play three concerts in Vienna, but those dates were canceled after Austrian authorities had thwarted a terrorist plot.

Following Swift’s London dates, she’s slated to perform a string of shows in Miami and New Orleans in October, before she heads to Indianapolis in November. She closes out the Eras Tour in November and December with several shows in Canada.
