A choir in one country sings another country's national anthem

I came across the 1 minute movie below through TED. I think it’s quite an interesting idea that a choir in one country sings another country’s national anthem. As described on YouTube in the text about the movie, I think this initiative has potential to change the way we think about other countries.

Apart from the French choir featured in the movie below singing the national anthem of the United States, you can see and hear Kenya sing for India here, and/or listen to Japan singing for Turkey here.
