I finally found the track on Limewire, I was actually prepared to pay for it. It's seems to be covered by James Horner, he does lots of movie music. It's only about 4:00 minutes long, about the length of the first video. I was listening to it today in between classes, and I have to say that it's highly entertaining.

That bit about South Africa is really interesting, that's a great thing to know. I've only been around North America and Europe, I haven't been to Africa yet. After watching this commercial it's really intriguing.
