Picture this: Two girls, cousins, growing up in the lush, tropical paradise of Hawaii, learn the ukulele at their father's knee. Singing the old, mournful island love songs with their mother, harmony and melody come as naturally as the hula.

Or this: Two girls gigging their way through Tokyo's garage punk scene come under the sway of leis and the tutelage of musical Svengali Hiroshi Asada, responsible for the original Pizzicato Five mondo onslaught.

Whichever version you choose to believe, Petty Booka's kitschy take on the '50s Hawaiian vibe is as intoxicating as a frangipani blossom.
