The moosebutter is a group of 4 acappella boys (read more about them in their website). Corey Vidal (the author of first video) aske them the permission to make a video using Star Wars theme.

All human beings are born free and equal in dignity and rights. They are endowed with reason and conscience and should act towards one another in a spirit of brotherhood.

60 years after its first read, it’s still too young.

But we are human, and we believe in Hope.

Happy Birthday, dear UDHR!
