Bruce Springsteen joined Zach Bryan as a surprise guest on stage during a show in Philadelphia this week for a performance of ‘Atlantic City’.On Wednesday (August 7), during the second Philadelphia show of Bryan’s ‘Quittin Time Tour’, the pair performed the iconic Springsteen track as well as their new collaboration ‘Sandpaper’.‘Atlantic City’, taken from Springsteen’s 1982 album ‘Nebraska’, is a stripped-down acoustic number with haunting lyrics and a spine-tingling sound.The pair sang the iconic chorus together: “Everything dies, baby that’s a fact/But maybe everything that dies some day comes back/Put your makeup on, fix your hair up pretty/And meet me tonight in Atlantic City.”They then went into ‘Sandpaper’ a Springsteen-featuring track from Bryan’s latest album ‘The Great American Bar Scene‘. The new project also features John Mayer and John Moreland.Concert-goers in Philadelphia have been posting footage from the shared moment on stage on TikTok.
