Taylor Swift's surprise songs from Night 2 of the Eras Tour in London, including a Hayley Williams appearance

The Eras Tour is back underway, so it's time for surprise songs once again.

Taylor Swift’s Eras Tour continued its international journey on Saturday night in England (afternoon in the United States) with the second of three shows in London. The now 14-time Grammy winner will be touring almost non-stop for the entire year, and at each show she adds two “surprise songs” to her 44-song, three hour plus set list.

For the second night of this particular stay in London (she is coming back for five shows in August), Swift invited a special guest on stage for the piano portion of the evening. On guitar, Swift played “thanK you aIMee” from The Tortured Poets Department mashed with “Mean” from Speak Now. At the piano, Swift was joined by Hayley Williams of Paramore to perform their song “Castles Crumbling” from Speak Now (Taylor’s Version).
