Exactly 50 years after forming, U2 returned to Dublin for a special concert at Mount Temple Comprehensive School, the very place where the band first met. Bono, referring to the group as "We've escaped from the lab," took the stage in the school's playground, where the band had first performed in 1976. The students gave the legendary rock band a warm reception, waving signs that read, "I love U2," "It's a beautiful day - no school," and even one that said, "Bono, my mum says hi!" The concert featured a mix of hits like "I Will Follow," "Vertigo," and "With or Without You," along with their latest single, "Silencio." Teachers had to manage excited students who climbed on each other's shoulders, but eventually joined in the celebration, dancing along with the music. The U2 story began in the same halls and corridors of Mount Temple Comprehensive five decades ago. In 1976, 14-year-old Larry Mullen Jr. pinned a handwritten note on the school noticeboard: "Drummer seeks musicians to form a band." Auditions were held a few days later in his parents' kitchen. Among the hopefuls were Bono (then known as Paul Hewson), The Edge, and Adam Clayton—though Clayton arrived wearing a full-length Afghan coat. The band, initially called Feedback and later The Hype, eventually became U2. They evolved from a scrappy punk group into one of the most successful rock bands in history. The band's early days were anything but glamorous. The first practice session was more talk than music, and some members were not even prepared. Clayton, who couldn't play the bass, was chosen for his "best hair," and Bono—who wanted to be the guitarist—showed up without a guitar. Despite the awkward start, the group began to attract attention. Halfway through the rehearsal, a group of screaming girls tried to climb the garden wall, which made Bono step in to save his friend from embarrassment. This moment marked the beginning of U2's journey to global fame. Back at Mount Temple, Bono paid tribute to the school for supporting the band's early development. He dedicated the concert to school counselor Jack Heaslip, who later became a "travelling pastor" on U2's tours before passing away from motor neurone disease in 2015. The band closed their performance with an orchestral version of "One," performed alongside students from Ireland's Music Generation program, which U2 helped fund. In the hours before the concert, U2 also announced their 16th studio album, Carnaval de Luz, set for release in November. The album includes a duet with Dolly Parton, who passed away last month. The track, "Torn," is described as a tender song about broken family ties and will be featured in an upcoming BBC News interview.
