Beautiful voices, I hope they're sing with there hearts, not the kava singing. There is a different, such song is sung when you praising God, in worship hour not when you drunk, in kava drinking you sing love song, that is appropriate to the occasion, I hope we all Tongan understand, as we so used to this habit, we can't separate the clean and the unclean, think about it,
I can tell this faikava happened on a Sunday hence why they are playing and singing gospel songs as that's how the Tongans roll. Other days, they'll sing all sort of tongan songs.
