Even though that's my post, I've gotta admit it's not quite right.
Here's a better description of the Hymn, from the absolutely divine fflyrics. (http://www.fflyrics.com/inorinouta.html)

The actual hymn is

Ieyui
Nobomeno
Renmiri
Yojuyogo
Hasatekanae
Kutamae

This is slightly different from what's in ShivaBlizzard8's post. It isn't "nobomenu" on the second line:p

And when you decipher the whole puzzle, what you get is

Pray, Yevon-ju
Dream, Child of Prayer
For ever and ever
Bring us glory
