Well that song that Wilford Halfmoon has explained. It is really important because it was a song that was used during a signing of a very important thing that had to take place between the different tribes. As you can see all these warriors and people riding horses and singing a song as they are riding into the campground before they have this big event. It is like a grand opening but yet you knew it was a song that was sung just for that purpose, for that special event. Maybe they were returning their warriors from battle or whatever, but it had to be a special event. Whereas if you were carrying the flute or singing a love song to someone that is certainly a different story altogether. The national anthem when it is sung it really means something, rather than just a song that they picked out of page 22.
