Hewson has served as at least partial inspiration for many Bono-authored U2 songs, going back to the track "Another Time, Another Place" from their 1980 début album "Boy". She helped Bono get through a bad period of writer's block during the lead-up to the 1983 "War" album, particularly in the composition of the lyrics to "Sunday Bloody Sunday". She inspired the personal themes in "New Year's Day", from the same record. That album and the accompanying War Tour brought financial success to the band, and Bono and Hewson moved into a three-level, three-room Martello tower in Bray. The group's 1984 song "Promenade" reflects both that location and the spiritual aspects of his desire for her.
