Alwyn is credited on at least two songs from her album “Folklore” and a few from “Evermore,” although he goes by a pseudonym, William Bowery.
Swift confirmed that the mysterious Bowery was Alwyn after fans began speculating. The musician confirmed that the two had written a few songs together while in COVID-19 quarantine.
“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.”
