World Vision Rally for the World's Poor Worship Service - Philadelphia Cathedral

It turns out Sunday's DATA rally on Independence Mall will conclude with a 4:00 Worship Service, featuring Jars of Clay, at the Philadelphia (Episcopal) Cathedral. (To paraphrase 2 Samuel 14:19, is not the hand of a Get Up Off Your Knees contributor with them in this? ...I'm guessing probably.) There is a PDF flyer available at the Cathedral's site. Michael W. Smith will also participate.
