Vertigo Tour in Lisbon

"The origins of the band were based on friendship. As we got older, there was a sense of group purpose. We took on a band ego and left our own egos checked at the door because if the collective wins, we all win. That makes it so much easier to deal with each other’s idiosyncrasies. Most bands break up because one or more members decides they’d be better off being solo. It’s more every man for himself." - The Edge on how U2 has been together for so long, 2023
