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.
