On Friday, May 6, KoAloha was part of a big event in San Jose at which the animated film about KoAloha was screened, Ohta San and Herb Ohta Jr. played in concert, along with others, three KoAloha ukuleles were given away in a raffle, and KoAloha ukuleles were made available for sale. (I think Ukulele Source, an ukulele store in SJ that sells KoAloha ukuleles, was also involved in this event.) I imagine that from April 30 on, the KoAloha people were preparing for that event. Your email message may have been overlooked or it may not have even gotten there. You should try contacting KoAloha again, maybe this time by phone.
