Under what pseudonym was Joe Alwyn credited on Taylor Swift’s “august”?

Joe Alwyn was credited as William Bowery on Taylor Swift’s “august.”

William Bowery was the pseudonym Alwyn used for songwriting credits on Folklore and Evermore. Swift initially presented the name without publicly identifying the person behind it, which led fans to speculate about the songwriter’s identity.

Swift confirmed Alwyn’s involvement in the Disney+ documentary Folklore: The Long Pond Studio Sessions, released in November 2020. She explained that he helped write “exile” and “betty,” and his songwriting contribution extended to “august.”

The name is sometimes confused with Nils Sjöberg, another Swift-related pseudonym. Nils Sjöberg was used for a writing credit on Calvin Harris’s “This Is What You Came For,” whereas William Bowery refers to Alwyn’s Folklore-era songwriting identity.
