This is the senior class of 2015 at Kahuku High School located in Hawaii more specifically the North Shore of Oahu. The seniors learned this number in 2 days...they did a great job.
@8:43 they performed the "Kaipahua Kura" which is their very own "Haka" or "war dance" from the Maori people of New Zealand.
Kahuku High is a very culturally diverse school with lots of school spirit and pride. Good luck to them!
