Steve Taylor has a perceptive comment on the addition of one line to the U22 version of "Until the End of the World," reflecting on the way small changes in U2's live performances deliberately recast the meaning and referent of a song to open up new ways in which it applies, or can be applied. (And, as he says, so often this is about remembering, widening the community to include someone from the past.) It makes a great addition to his excellent list of things worship leaders can learn from U2. Believe me, this insight can profitably be drawn upon by even the most "stick to the book" liturgical congregations -- think offertory sentences, an extra subordinate clause in intercession invitations, an inserted phrase in the way the peace is bidden. It doesn't take much. Or rather it does, but the "much" it takes is called intentionality.
