I suppose nobody wanted to give a speech after this :)

New Zealand wedding haka moves millions - BBC News (http://www.bbc.com/news/world-asia-35370983)

As a DJ, I once, many, many, MANY years ago worked a wedding here, in the middle of the U.S., for a deaf couple that the best man and the guys did a Haka. It was very cool.

/the answer to the question of how do you DJ a dance for deaf people is bass. Lots of bass. And lights.
