Brandon Flowers continues to bring out all-star guests at his Desired Effect concerts as he treks through Europe: After singing alongside Pretenders’ Chrissie Hynde during a London show, the Killers singer was next joined by New Order’s Bernard Sumner at his Manchester gig Sunday night, performing the classic “Bizarre Love Triangle.” The collaboration comes just days after it was revealed that Flowers was in the studio working with New Order on an unspecified project.
