U2 in Dublin night I (2009)

"It's a classic, especially on the album. But we have to remix it for a single. We have to figure out how are we going to get that song on MTV? Those songs do not come around easy. The melodies of most songs are A-B, A-B, and this is A-B-C-D. The construction of it is unique. And I want you to want us to have that song out on the radio." - Bono on Original of the Species, 2005
