U2 in Houston

"As we do before every show, we pray. Sometimes it can feel as if we’re strangers, praying to find the intimacy of a band that could be useful to our audience this evening. Useful? To music. To some higher purpose. In some strangely familiar way we are changed. We begin our prayers as comrades; we end them as friends finding a different image of ourselves, as well as the audience we’re about to meet, who will change us again." - Bono
