Local musicians at Ferdinand’s restaurant, Magellan Sutera, Sutera Harbour Resort
The group’s name is HINAVA, and Jessel Yansalang told me later that they are considered Sabah’s answer to Filipino strollers.
Post here if you know their individual names and anything else about them. I gave them the link to this website, but didn’t want to disturb their work by getting them to write down all their names. They are definitely Sabahan, I asked them.
