As this site complains (along with the next link), the video does nothing to raise confidence in Nigeria. The song is popular in Cameroon, and is apparently based on a tract authored by Nkem Owoh.
UPDATE (December 10, 2009): Nkem Owoh was recently kidnapped while driving down the highway in eastern Nigeria, and the original ransom was 15 million naira ($99,000), but allegedly reduced to 1.4 million naira and his car.
