Wait...
Wait, so you found this in a piano book? That makes it NOT an original piece. That makes it against NG Audio Portal rules (pr pretty much anywhere else). But that doesn't matter too much here because this song obviously doesn't have huge copyrights attached to it.
Anyway, the song is okay. But why would you bother uploading something you didn't write yourself? To provide flash-makers with more music? Fair enough, but I'll say again - but the AP is for original stuff only!
