St. Nicholas Greek Orthodox Church, which was built in the shadow of the World Trade Center and destroyed on the 9-11 Attacks, held a Divine Liturgy and memorial service near the location where the church building formerly stood to celebrate their feast, St. Nicholas' Day (December 6).

The page below has a video report by the NY1 news channel on the service. At the end, there's a brief shot of a bagpiper (can't tell what the tune is); I presume it was during the memorial service after the liturgy.
