Not officially released. There's only the karaoke mix which is the same arrangement as the 4 minute single version, and of course there's 'Forever'.
It's not too difficult to edit together a full instrumental as I recall.. I think it still must include one line at the end which isn't instrumentalized in the karaoke.
I know about 'Forever' which is gorgeous but I preffered one that's just like the original song. I don't mind if there's still a few lines in it but mostly instrumental.
No problem.. I get great upload speed at Mega.. I actually hate Rapidshare. LOL
23k upload at RS.. 99k upload at Mega. *sigh* ;) link
