Taylor Swift’s ‘The Tortured Poets Department’ has been swamped by Swifties.Swift dropped the album yesterday (April 19), before later revealing that it is in fact a double album, sharing 15 additional tracks. She has also released the official video for the single ’Fortnight’, which features Post Malone.One unexpected side effect of the album’s release has seen hundreds of Swift fans flock to The Black Dog in Vauxhall, South London, after Swift sang about it on the song of the same name.“And your location, you forgot to turn it off / And so I watch as you walk / Into some bar called The Black Dog / And pierce new holes in my heart,” she sings.The song is thought to address her ex-boyfriend Joe Alwyn, who lives in the same area as the pub.The staff at The Black Dog are now frantically searching through their CCTV archives to try to find any evidence of either Swift or Alwyn visiting the premises in the past.A post shared by The Black Dog Vauxhall (@theblackdogvauxhall)“This is the Taylor Swift Effect – anything she touches goes viral,” said Amy Cowley, who works at the pub (via the Standard).
