In this series, the legendary Paul McCartney displays his talent in a genre he's not usually associated with: classical music. The Choristers of Liverpool Cathedral and a stunning philharmonic orchestra perform "Liverpool Oratorio," which McCartney created with fellow musician Carl Davis as a chorale piece. From the first movement, "Andante," to the last, "So On and On the Story Goes," Sir Paul's opus is a gripping meditation on war and peace.
