"It was completely off the cuff, an accident," Alwyn told Vulture about writing the first verse of "Exile." "She said, ‘Can we try and sit down and get to the end together?’ And so we did.

It was as basic as some people made sourdough." Joe Alwyn revealed writing songs with girlfriend Taylor Swift was "an accident."  The actor doesn't sing on the track "Exile," the vocals were done by Bon Iver.

However, Alwyn also helped with the song "Betty," writing the chorus for Swift. "I’d probably had a drink and was just stumbling around the house," Alwyn told the outlet. "We couldn’t decide on a film to watch that night, and she was like, ‘Do you want to try and finish writing that song you were singing earlier?’ And so we got a guitar and did that." Alwyn has credits on two of Swift's albums, "Folklore" and "Evermore." He wrote under a pseudonym, William Bowery.
