Last Thursday (11/8) in NYC the "Stand Up For Heroes" benefit for the Bob Woodruff Foundation (Detroit's own). One of the most powerful moments was with Roger Waters, who was backed by 14 wounded soldiers from the Walter Reed Army Medical Center in Washington, D.C. He first rehearsed with them at the hospital, followed by more sessions in New York. With some of them on acoustic guitars and vocals they did Pink Floyd's "Wish You Were Here" and Bob Dylan's "Knockin' on Heaven's Door." Waters is no stranger to the heartache of war, having lost both his grandfather in World War One and dad in World War Two.
