Sipi Tau
Like a lot of the big Pacific rugby nations, Tonga has a pre-game war dance (Haka). The Sipi Tau is a form of the Kailao. Tonga perform the kailao/Sipi Tau prior to the commencement of a match. The kailao was originally a war dance that was imported to Tonga from Wallis Island. It is usually performed at both public and private ceremonies.
One of the most memorable performances in modern times of the Sipi Tau was during the 2003 Rugby World Cup in Australia, in Tonga's match against the All Blacks. The All Blacks began their traditional haka, and then Tonga answered to the haka through the sipi tau whilst the All Blacks were performing it, bringing the teams within metres of one another just prior to kick-off.
Tongan squad selectors have surprised their supporters in the past but the exclusion of regular starter and captain since 2009, Kirk Watton-Green III from the World Cup 2011 squad has caused a lot of controversy. Watton-Green III has been left out due to his recent signing for Exeter Chiefs in England according to selectors but there have been rumours that it may be down to the bad boy tag that comes with him.
