What is the name of the group that sings the song "Pu Pu a o Ewa" (sometimes called Pearly Shells) from the movie "Donovan's Reef" starring John Wayne and Lee Marvin?

I don't know if this person is the "singer" exactly but the original score comes from Cyril Mockridge.

I'm not finding anything official:

"The group that sang the Hawaiian version of Pearly Shells (in the movie Donovan's Reef), is Kamehameha School Glee Club. To my knowledge there is no recorded version by them."

Another person states:

"I found an acappella version of 'pupu a o ewa' by the the St. Caterine church choir. They are the group that did the movie version in "Donovan's Reef". It is an LP recording titled "aloha oe e malia."
