Lorde, Flight of the Conchords write song for New Zealand’s Rugby World Cup side

Some of the biggest Kiwi stars have come together this week to write a charity “fight song” for the country’s Rugby World Cup side.

Lorde, Flight Of The Conchords, Kimbra and, somehow, Lord Of The Rings director Peter Jackson are all on board for the song, which supports the Cure Kids charity, helping to draw attention to Batten disease.

A video has been released of the acts joking about and working on the track in the studio. It also features a unicorn, obviously, and a wonderful number of rugby lyric puns.
