The Manu Siva Tau is a Samoan war dance, performed by the Samoan sporting teams before each match.
The national rugby union team used to perform the traditional 'Maulu'ulu Moa' on tour. Prior to the 1991 World Cup, the 'Manu' war chant was composed, it was considered to be more effective at psyching up players.
The national Australian rules football team performs the Siva Tau at its International Cup appearances.
In WWE, The Usos, as faces, performed the Siva Tau as part of their ring entrance.[1]
The Toa Samoa national rugby league team also perform the Siva Tau before each match (with the "Toa" replacing "Manu" in the words).
The song "Le Manu" by the New Zealand metal band Shepherds Reign has the lyrics of the Siva Tau as performed by the Manu Samoa.[2]
