"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."

In 1999, a bag holding personal papers and a laptop computer containing lyrics for the ATYCLB album was taken from Bono's car. Bono offered a reward of £2,000 for the return of the computer. An Irish man returned the laptop after having bought it for £300 thinking it was from a reputable source. He realised it was Bono's when he saw a picture of the singer's child Elijah Bob on the screen, prompting him to contact U2's management.
