Would anybody happen to know sources for GTO's (Great Teacher Onizuka) opening and ending singles? I spent hours looking for them during the past few days (no exaggeration), but in the end I found nothing but one barely alive batch torrent of Porno Graffiti songs that also contains "Hitori No Yoru" (though I don't know if it's a single or a TV size version).

What comes to the rest of them, I did find an insanely large collection torrent on some japanese site and from what I could understand (it was largely in japanese), it might have contained almost all of them. However, that torrent was totally dead, as the tracker wasn't anymore on the server, and DHT was also as silent as an average grave.

To be specific, the singles I'd mostly be insterested are:

Op2:
"Hitori No Yoru" by Porno Graffiti

Ed1 & Ed2:
"Last Piece" by Kirari
"Shizuku" by Miwaku Okuda

Maybe this is a lost cause, but it never hurts to ask here, where so many knowledgeable people visit.
