Spirit, Breathe

I didn't realize until Mockingbird's post here (a good read) that Bono has often changed the last chorus of "Breathe" into "Spirit, breathe.

He didn't just invite the audience on his otherworldly journey, he also invited Someone Else: at the end of the first song, "Breathe", he closed his eyes and knelt slightly. With one hand holding the microphone and the other palm-toward-heaven, he pleaded, "Spirit breathe."

"I found grace, it's all I found...Spirit, breathe".. 8:11ff:
