“William Bowery is Joe, as we know,” she says in the film, via ET Online. “And Joe—Joe plays piano beautifully, and he’s always just playing and making things up and kind of creating things.” Swift has been linked to Alwyn, an actor who’s appeared in films including Harriet and The Favourite, since 2016. His alias (which fans connected to the Bowery Hotel, where he and Swift were spotted shortly after they went public with their relationship) is listed as co-writer on the Folklore songs “Betty” and “Exile.” In the documentary, Swift elaborates on how the collaboration came about.ae0fcc31ae342fd3a1346ebb1f342fcb Alwyn is responsible for the chorus of the track “Betty,” which is about a teen love triangle, the artist explains. (By the way, the fictional subjects of the song—James, Inez, and Betty—are actually the names of the three children of Swift’s pals, Blake Lively and Ryan Reynolds. They hadn’t shared the name of their youngest [the eponymous Betty] publicly before this, evidently choosing to do so through the lyrics. Just more proof that Swift loves lacing secret codes into her music!) According to Swift, it was her boyfriend who gave her the idea of writing the song from the perspective of a teenage boy. “He was singing the chorus of it and I thought it sounded really good from a man’s voice, from a masculine perspective,” she says in the film. “I really liked that it seemed to be an apology.” Swift also shares that this was the first time the couple had ever written together. And though it could have been “really weird,” they used quarantine as an opportunity to try it. “Betty” led to Alwyn also writing on “Exile,” Swift’s duet with Bon Iver vocalist Justin Vernon. “‘Exile’ was crazy, because Joe had written that entire piano part and he was singing the Bon Iver part,” Swift says. “And so, I was entranced, and I asked if we could keep writing that one.” The singer doesn’t comment on why Alwyn opted for a pen name or why they decided to reveal his work on the album now. But Swift’s fans can hold their heads high knowing that they correctly solved another one of her puzzles.
