What pseudonym did Joe Alwyn use when credited on Taylor Swift’s Folklore?

Joe Alwyn used the pseudonym William Bowery for his credited work on Taylor Swift’s Folklore.

Alwyn contributed to Folklore as a songwriter and producer under that name. Swift later confirmed that William Bowery was Alwyn, ending the speculation surrounding the otherwise unfamiliar contributor credit.

The name is connected to two personal references: William was Alwyn’s great-grandfather’s name, while Bowery referred to an area of New York City where Alwyn had spent time. The pseudonym allowed him to participate privately during the album’s creation.

The credit is relevant to “august” because the song’s credits and the album’s production history include Alwyn’s later-recognized contribution. Jack Antonoff and Swift remain the song’s principal publicly identified collaborators.
