At Dublin’s Mount Temple Comprehensive School in 1976, four lads with limited musical ability put a band together. Paul David Hewson called himself “Bono,” singing and playing guitar badly. David Evans called himself “The Edge,” and played guitar. Adam Clayton used his real name and played bass. Larry Mullen Jr. played drums and percussion. They called their band Feedback, and then The Hype and played some gigs in 1977. When they were presented with six possible band names, they settled on U2 because of its multi-meanings. They didn’t know what they were doing at first and at some point Bono dropped his ambition to be a guitarist, and just sang. And now, 40+ years later, they’re still at it, recording and performing, the four original guys and the same name. And they’ve done well, releasing 14 studio albums, selling more than 170 million records worldwide, winning 22 Grammy Awards, and being inducted first try into the Rock and Roll Hall of Fame in 2005. Gratified by and grateful for the giant success of a bunch of clueless, 16-year-old Irish kids, U2 as a band have stood up and made their voices heard for social justice and human rights campaigns: Amnesty International, Jubilee 2000, the ONE/DATA campaigns, Product Red, War Child, and Music Rising.
