U2’s 1991 song “One” is a soul-stirring anthem of unity and forgiveness that almost never happened — it emerged from a jam as the band nearly split during the making of Achtung Baby. With Bono’s heartfelt vocals pleading “we get to carry each other,” the ballad’s ambiguous lyrics have been interpreted as everything from a conversation between lovers to a message of global togetherness. The song became a highlight of the album and a massive worldwide hit. It was later used to raise funds for AIDS charities, further amplifying its message of compassion. Often performed with tens of thousands singing along, “One” has endured as one of U2’s most beloved and spiritually uplifting tracks.
