Great topic. Lights of home was a spiritual highlight of the tour for me. It’s a prayer, with Bono kneeling, making the sign of the cross and all that. It’s a vulnerable moment. I think LoH is central to understanding the whole album/ tour. We learn that Bono is finding the light in Jesus’ eyes. Blackout is about losing the light, and the ending with 13 is about passing on the light he’s found.
Other spiritual highlights: Streets, Magnificent, Wake up deadman. O yeah, Breathe and The Miracle (I think they are related).
