Idolem urodo iatu a wi rot,		Tori wa utai odoru melody,
Ukufu kush onuoy nehawuoch.		Chou wa hen you no shukufuku.
Etia di ukoik ura nakurah,		Harukanaru kioku idaite,
Enadu yoimi nnesar urugem.		Meguru rasen ni mi o yudane.
Eteako ich atak,		Katachi o kaete--
Ureatu tso oodah--		Hadou o tsutaeru--
Amia wibo koro yonneie!		Eien no yorokobi wa ima!

So the original song is Japanese, but sung backwards. Although it's made up mostly of sentence fragments, one can eke out a rough translation:

The birds sing a dancing melody,
Butterflies are a strange blessing.
Embrace distant memories
And entrust yourself to a circling spiral.

Change form--
Tell [others] of this wave motion--
Eternal joy is now!
