"Dirty Day is a father and son song. 'It's a dirty day', was an expression my dad would use and there is a lot of him in there but it was also influenced by Charles Bukowski, the great American writer and drinker. The song is about a character who has walked out on his family and, years later, meets the son he's abandoned. It's not about my father but I used some of my dad's attitude in it."

Part of the inspiration for the lyrics of One reportedly grew out of a note Bono had sent to the Dalai Lama declining an invitation to a festival called Oneness. The note included, in part, the line, “one – but not the same,” a line which would later appear in the song’s lyrics. That idea of “oneness,” Bono would later say, was a key concept for the song.
