What pseudonym did Joe Alwyn use for his Folklore songwriting credits?

Joe Alwyn used the pseudonym William Bowery for his songwriting credits on Folklore. The name was initially unexplained when the album was released, leading fans and media to speculate about the identity behind it.

Swift later confirmed that William Bowery was Alwyn. He co-wrote “Betty” and “Exile,” and he also received a producer credit on “August,” although “August” was written by Swift and Jack Antonoff.

Alwyn’s involvement became part of the album’s unusual creation story. Because the record was made secretly and remotely during the pandemic, collaborators exchanged instrumental files, vocals, lyrics, and ideas away from traditional studio routines.

The pseudonym is sometimes incorrectly attached to every Folklore song. It is connected to Alwyn’s specific songwriting and production contributions, not authorship of the entire album.
