Ray Buhen, one of Don The Beachcomber's original bartenders, who went on to open his own Tiki-Ti Bar in Los Angeles, introduced a third spelling. In his book Sippin' Safari, Jeff Berry features a recipe for a Hula Hula from the personal notebook Ray used in 1934 when he first worked as a bartender at the Beverly Hills Hotel, "1 ounce orange curaçao, 1 ounce gin, 1 ounce fresh orange juice."
