Before this album came a single, a song that is played on its own, called "I Will Follow". It became popular and was played on college radio stations and made people know who U2 were. "I Will Follow" was thought of as a Christian song. This was because most of the members of U2 were Christians. None of the band members has said that that is true. This album is somewhat about Bono's life as a child, and his mother's death when he was 14.
