"Who is William Bowery?" is the big question of Folklore's release. Swift listed him as one of her co-writers on her Instagram announcement ahead of the album's release, but he doesn't seem to actually exist: no one can find proof of his identity or any other credits.
The assumption, then, is that Bowery is a pseudonym for someone — but who? The leading theories right now are that Bowery is actually Swift's brother, Austin (who already used a pseudonym to do a cover of his sister's "Look What You Made Me Do"), or her current boyfriend, Joe Alwyn. Will we ever find out? Who knows.
