The Scottish hit makers followed Simple Minds and Anne-Marie – who headlined the venue on June 18 and 20 respectively – with a set which covered their illustrious 35-year plus chart career.
Opening with City Of Love, Queen Of The New Year and Fergus Singers The Blues, Deacon Blue then gave the 8,000-strong sold-out crowd Your Town, Chocolate Girl, Real Gone Kid before a stunning finale of Dignity and Wages Day.
Opening the show was chart-topping indie outfit The Lottery Winners.
Next up at the Scarborough venue is music legend Sir Tom Jones on Wednesday June 26.
