GTO. Some help please.

Does anyone know the names of the songs that come on at each ending of GTO? There's two different ones, can someone tell me the names of them and the artists of them?

sry...i'm a little slow, whats gto?

Maybe I should have mentioned, Great Teacher Onizuka, the anime.

I found one of them, Shizuku by Miwako Okuda, now I just need to know what the other one is called and who it's by.
