Joe Alwyn is credited as a co-producer on Taylor Swift’s “august.” He worked on the track with Swift and Jack Antonoff, although Antonoff supplied the initial instrumental.
Alwyn’s involvement became part of the wider Folklore credits and production story. During the album’s creation, Swift collaborated remotely with several musicians while quarantine limited in-person studio work.
The name William Bowery is a frequent source of confusion. Alwyn used that pseudonym for songwriting and production credits on Folklore, but “august” is credited directly to Joe Alwyn in the song’s production information.
Alwyn was not the song’s sole producer or its only writer. Swift and Antonoff wrote the song, while the production credits recognize the collaborative nature of the recording.
