Here's something you want see at the start of a sports event too often: Streamed Video of new Haka Torrent of the new Haka: http://www.mininova.org/tor/100184 Torrent of the whole rugby match: http://www.mininova.org/tor/99910
Here's a quick thought, we had the Ernest Givens' Electric Slide, Falcon's Dirty Bird, Joe Horn "Hiding the Cellphone" and David Carr "Losing the Cellphone," I think the Haka would make a fantastic TD celebration. Even if the fans aren't impressed, it ought to strike some fear in the ppposition's psyche.
The haka or hakka is older than most countries. There is nothing "new" about it. It's also, primarily a traditional aspect of Maori culture.
