Is this Betteridge's Law?
Smeagol is that you?
He's Australian. It's supposed to be upside-down.
Oh, a centrist, are ya? Get 'em, lads!
You've been searching for this song for at least 12 years? Nice!
So did I, and I saw the Australian version. It did not save me.
You piqued my curiosity. Here's what I found:
A thread with no answers referencing a dead website. Dead website also has no answers but speculation. One person posted "mediafire. com/?xfj7p38y97z8dey - 04 Fly.mp3" which is likely either the same track, the actual Jars of Clay song, or possibly a virus. I couldn't get the link to work.
A user on a Final Fantasy forum had a copy of the song, along with at least one other fake Jars of Clay song. That user is still semi-active if you want to try getting in touch.
(Not linking to it, but) a music piracy website which has the track listed under Jars of Clay, but no copy of it available.
What a mystery. The only idea I have is that someone figured they could "publish" their song by putting it on piracy websites under Jars of Clay's name, but the background vocals make me doubt that. I'm not sure someone would have the resources to do that but not to publish.
I like the cut of your jib.
New prank idea.
I see what you did there...
And to that I say...
Are you /srs or /j?
