Last spring, 60 Minutes correspondent Bob Simon met Polish priest and musicologist Piotr Nawrot, who took him on an incredible journey.

Piotr Nawrot has been searching for the remnants of musical manuscripts which he was convinced were hidden by the Indians after the Jesuits were expelled from Latin America 300 years ago.
