Waikiki showroom veteran Jonathan Kaina was co-emcee and guest entertainer when Gigi Ko, left, and her sister, Isabella Rose Monzon, presented “Viva Las Vegas,” a fundraiser luncheon for the Organization of Chinese American Women, Saturday at the Pagoda Hotel. Kaina and Ko shared emcee duties throughout the event. He also entertained the crowd solo with a medley of oldies everyone of a certain age remembered and could sing along with.
