In September 1976, 14-year-old Larry Mullen Jr. pinned a handwritten note ("Drummer Seeks Musicians To Form Band") to the noticeboard at Mount Temple Comprehensive Schoolin Dublin. On September 25 of that year, Paul Hewson ("Bono Vox"), David Evans ("the Edge"), Dik Evans ("the Edge's brother"), Adam Clayton, and Ivan McCormick joined Mullen for their first rehearsal, under their original name Feedback. It was later changed to the Hype and finally, U2. Today, exactly 50 years later, the band returned to Mount Temple to perform for 1000 students and staff. The setlist included "Out Of Control" for the first time since 2018, "I Will Follow" for the first time since 2019, and the live debut of their new single "Silence." U2 then headed over to Bewley’s Grafton Street Café for a second surprise set.
