This is old, but any mention of Aya is well worth it. You get a dictionary, and look up the word idol, and it's bound to have a picture of Aya Ishiguro.
In this clip she schools the other members on what it means to be an idol...when you are in front of the camera, you put all the shit out on the table and you don't hold back.
You only have so much chance to make your mark, and to help improve the song or performance you are working on. Another thing about being an idol - other idols look up to you, they can see that you are doing it like there isn't any tomorrow..... Ayappe, here's to you for being a super idol and a super mom!!
