"The Edge is one of these people, that you wouldn't see him doing his homework. But he slopes off in the evening and he would be up for a couple of hours writing a song. There were songs that would come from him that were fully formed. Sunday Bloody Sunday was one of these songs. Vertigo is another example."
- Adam on U2's recording process, 2021
