At the very least, if it's a fake, the use of samples from the NFB documentary
Circle of the Sun (1960) in Circle is well-placed, and thematically appropriate to the album, which seems to be related to the indigenous people of Alaska and western Canada. Of course, it's
known that BoC reference this documentary. Still, well done on whoever did that.
Found by googling some of the lyrics, via this
bachelor's thesis:
It the movie, though, there is only a few people. The camps are getting smaller every year. According to Standing Alone (1960), that year, there were twenty tepees, but twenty years ago there were fifty. In the past, there used to be hundreds of men from different tribes as well (Low, 1960). This tradition is fading away but, surprisingly, it is still being conducted until this day.
The Sun Dance used to be a very important ritual, but with each generation, it is losing its significance.
“But old way life is dying and most of the Bloods (=Kainai) don’t even go to the camp now. The children don’t know what it’s about and when they grow up they will forget they were once at the camp. They are the dying echo of its people’s history.”(Low, 1960, 2:28)
Next to the dances, the film also shows smaller ceremonies where they pray and sing religious songs. They celebrate nature and all creations of the Sun; the source of life. They also emphasise the importance of a circle.
“The power of the world works in a circle. The sky is round. The stars and earth are round. The seasons form a great circle. The life of a man is a circle from childhood to childhood.” (Low, 1960, 16:22)
