Old Umatilla Song

I sang this song with the boys after just a couple of run-through's. Adam was taught this song by his grandpa, Malvin Jamison, but hadn't practiced it for quite a while and most of the boys only heard it for the first time just now.
Clockwise from myself:
Hiyuum Nowland, Truman Brown, Adam Bauer, Myles Minthorn and Rion Johnson.
