Bono: (from the book Race Of Angels): "I remember getting Edge an echo unit and saying, Use this, because this will get us to another place. This will get us outside of the concrete - into the abstract. I just knew that the echo unit would do that. Atmospheres - we were very interested in atmospheric music. Punk started to look incredibly limited. It seemed so rigid, not just musically, but it started to have a rulebook and codes. And then I remember Joy Division came along, and I really related to that, because of the moods and atmosphere. And David Bowie's Low - that was very interesting. That's where we were. So we started with that thing." >>

This was U2's second single. It was released only in Ireland and does not appear on any albums.

This went to #1 in Ireland, convincing Island Records to sign the band.

The B-side contained an early version of "Twilight."
