U2 in Saint Paul

"The songs were written for the stage more than they were written for the radio. In a small venue to create a kind of energy and excitement, it requires everyone to be fully committed to be at a 10. And what that meant for Bono was singing at the top of his range more often than he would than if we written songs for the comfort of our living room." - The Edge on Bono singing in high keys in the 80s, 2022
