One of the sounds that the Champions League Twenty20 governing council will want to disassociate with is the vuvuzela which has been banned from cricket stadiums in South Africa amongst other things.

Gerald Majola stated emphatically that the sounds of the FIFA WOrld Cup 2010 would not be a part of cricket celebrations in the Twenty20 tournament, "We have had various discussions with key stakeholders and we feel the vuvuzela is not appropriate for cricket.
“Fans at CLT20 matches will be treated to non-stop music, dancers, cheerleaders, and of course, the main attraction, the action out in the middle.
“There is no doubt that the vuvuzela added to the atmosphere during the recent FIFA World Cup, but it is certainly not the sound of cricket.”
Amongst other things that cricket fans cannot carry to the stadium during the Champions League Twenty20 2010 in South Africa include alcohol, illegal drugs, pets, air/blow horns, braai material ( for barbecue parties ), bottles (except for those in plastic), fireworks, explosives, but cigarette matches, deos are allowed!
