A rock group returned to the specific school grounds where they originally formed to mark five decades of musical activity.
Their performance included an arrangement of One performed by pupils from Ireland's Music Generation education programme.
The band had assisted in funding and establishing that educational initiative fifteen years prior to this event.
During the concert, educators intervened when children climbed onto each other's shoulders to reach the stage.
Many teachers subsequently joined the audience in dancing as the music continued.
Originally known as Feedback before adopting the name The Hype, the group evolved into U2 through significant stylistic changes.
They transitioned from a punk-influenced formation to stadium-sized rock acts capable of drawing millions of fans and critics alike.
Albums released during the 1990s incorporated electronic elements, dance rhythms and ironic themes on records such as Achtung Baby and Zooropa.
The Zoo TV tour introduced innovative stage design featuring extensive multimedia screens and satellite transmission systems.
Bono made nightly prank telephone calls to the White House during that era of touring.
A new studio album titled Carnaval de Luz was announced following a period of intense rehearsal sessions.
Halfway through practice, a group of young women attempted to scale the garden wall surrounding the venue.
The upcoming release features duets with Dolly Parton alongside tracks from previous projects including Days of Ash and Easter Lily.
Anthems such as With Or Without You and Beautiful Day rely on distinctive guitar tones and lyrics focused on human connection.
Those earlier works addressed serious global issues in EPs like Days of Ash which covered violence in America, the war in Ukraine and conflicts involving Israel and Palestine.
Carnaval de Luz serves as a concluding chapter to this sequence of recent musical output.
The band's journey from scrappy beginnings to global icons is being celebrated at their place of origin.
