In 1983, as the singles “New Year’s Day”, “Sunday Bloody Sunday” and “Two Hearts Beat as One” were becoming MTV and radio staples, U2’s reputation as a must-see live act was being made in venues across the world (and immortalised on the Under a Blood Red Sky EP and accompanying concert video). Bono’s natural flair for the dramatic included scaling amp stacks and scaffolding and just generally getting accustomed to commanding the unwavering attention of an ever-growing number of people. “My idea of a performer is one that might leave the stage and you might find them in your life, on your lap, following you home and mugging you in the alley, making you tea, whatever it is,” Bono told Zane Lowe in 2017. “That comfortable distance, we’ve always tried to attack as a band, between the audience and stage, we tried to smash that.” The shows behind their third album War showcased those three hits as well as their 1980 calling card “I Will Follow”, but it was lesser-known songs like “11 O’Clock Tick Tock” and “The Electric Co.” that drove home the idea that this band’s appeal was not about hits—no matter how many they’d wind up amassing—but unmatched energy and chemistry. Closing out the shows on this tour and for many tours to come was “40”, the hymnlike final track on War that famously kept crowds chanting its refrain long after the band were back on their bus.
