from the preview image alone, i thought that was Ayaya. but that's probably partly because i never would have guessed Aichan was on a show alone, much less all those years ago.. and i know Ayaya has been on that show a lot.
sometimes i think i hate Tsunku, but then something like this happens and i realize i'm just kidding myself, the guy is an evil genius and i will always love him for it.
the song is a-freaking-mazing. they sounded average on their own, but together it elevates it to something that makes rainbow drip out of my ears. i hope they perform these songs together live!!
