From the comments on another video - this was IZ's last live performance. The 3 who came up on stage, to his right was Moon( brother in-law), to his left were members of the Makaha Sons( the Koko brothers). They were on no speaking terms since IZ's departure of the band and start of his solo career. The Hawaiian in the audience that was shedding tears they kept panning to is Keali'i Reichel. This was a historic night in Hawaiian music as the Makaha Sons of Ni’ihau finally reach reconciliation with braddah IZ. I was to young to remember this, but my pops, a Kanaka, 3rd generation, born and raised Lahaina says that this night was more memorable than his wedding night
