"What band at our level would play 10 songs, seven from the new album and three from our first album? The reason we do that is because this album and our first album have very similar themes. The first is an ode to innocence, as it's being held onto. The latest is an ode to innocence, as it's been remembered, with the thought that you can get back to it." - Bono on the Vertigo Tour, 2005
