U2 Berlin Olympic Stadium July 12 2017

"The funny side of this is, like, with this album, everybody's trying to say, 'U2, the next this, the next that.' You get record-industry people saying, 'As big as the Beatles — what's the name of the album?' 'The Joshua Tree.' 'Oh yeah, oh right.' It's not exactly Born in the Joshua Tree, or Dark Side of the Joshua Tree. It sounds like it would sell about three copies." - Bono, 1987
