When Simple Minds released Once Upon A Time on 21 October 1985, they were no longer the underground art-rock outfit that had emerged from Glasgow's post-punk scene in the late 70s. By this point, they were international chart-toppers, riding the success of Don't You (Forget About Me), the soundtrack anthem that had made them household names across America. But Once Upon A Time would do more than cement their fame, it would define the sound of mid-80s stadium rock and mark the band's full transformation from cult heroes to global icons.
