"Vuvuzela Orchestra 2010 Songs" are available on iTunes.

"The Vuvuzela Orchestra uses six tuned Vuvuzelas to play rhythmic chord arrangements of the wonderful songs South African soccer fans play and sing at stadiums. The stadium is filled with many fan groups making rhythms, dancing and singing with their vuvuzelas but each group plays their own rhythm which is why these sound like noise when you hear them on the TV screen rather than in the stadium.
The Vuvuzela Orchestra uses an ancient African music making principle in which each player only has one note to play and collaborates with all the other fans in the stadium to make music (including the much maligned standard issue Vuvuzela!!!). Come and make music with thousands of fans for the 2010 Soccer World Cup."
