Footage of firefighters from American Samoa battling California wildfires has surfaced online, showing the men singing a touching hymn as they walk through the Shasta-Trinity Forest.
The firefighters sang a Samoan Christian hymn, reportedly called Fa'afetai i le Atua, which reportedly means a thank you to God.
A number of reports identify the men as Crew 61 from the Helena Fire Department in Northern California.
A commenter on YouTube says every child in the islands knows the song from Sunday School.
