Churches and the Fall of the Berlin Wal l- November 9th marks the 20th anniversary of the fall of the Berlin Wall, yet the St. Nikolai Evangelical Lutheran Church in Leipzig hasn't changed much since the 16th century, when Bach played the organ here. Today tourists flock to hear how Christian Fuhrer, who became Pastor in 1980 when the world outside the church was divided by the Cold War, began holding weekly prayers for peace. Correspondent Deborah Potter reports how this tenacious pastor started a revolution that grew out of the church- that helped bring down the Berlin Wall.
