Kazuki & Naoto are playing the theme song of "HAWAII FIVE-O". They really love this program, and never missed a single episode shown in Japan. Both boys memorized the song, and arranged it by themselves. They were excited and pleased to perform their favorite song in front of many people on the stage at the Ukulele Festival 2012. Kazuki is 14 years old and Naoto is 11 years old. Thank you for watching. Hope you'll enjoy!!
