US Orange Order Documentary

A Documentary shot in Northern Ireland by a U.S. film crew following Maghera Sons Of William LOL 209, Northern Ireland & Sons Of William LOL 1003, Birmingham, Alabama, USA.
I believe this was aired on PBS in the USA. The Alabama based Orange lodge comprises Anglican / Episcopal Bishop, Rev Paul Zahl and other ministers. They have been regular visitors to the South Londonderry Twelfth in recent years. The 32 minute documentary is viewable in 5 parts here
