Beautiful Day: I pictured a mangled and beaten up Bono washed up on a beach as the song starts. Ragged as if he just narrowly escaped a disaster and lucky to be alive, he wanders around the city appreciating life and all the beauty in it.
Kite: I always pictured the video of this song would follow the life of a boy flying a kite at the beginning and slowly evolving through his life, all the anger, hurt, heartbreak and joy along the way, until it ends with the boy as a man with his own son/daughter flying a kite.
Mothers of the Disappeared: A night time shot of a guerilla war camp in South America and as the music comes in, the soldiers get restless as they see little lights coming on through the trees in the distance. They get their weapons aimed but before one shot is fired, they see veiled women walking out holding candles and they walk through the encampment as the soldiers lower their guns.
In a Little While: The video would start with one member of the band lying asleep in front of a door in the morning sun and the video plays backwards and we see a story unfold of a them having a very drunk night pursuing a very beautiful woman only to end in tears and him lying at her door in a drunken stupor
