For one thing there are two identical versions of this song on the site, but nevermind that. (http://www.animelyrics.com/jpop/sakamoto/thegarden.htm) (http://www.animelyrics.com/anime/rahxephon/garden.htm)
If you've ever heard this song you'll know that most of the song is a main English melody sung by Conte. However, during the chorus is a Japanese counter-melody sung by Sakamoto, which is in neither of the versions we have posted. I've never seen physical liner notes for the song, so I don't know if it's included, but I also can't find consistent kanji for it online, with the exception of in the subtitles of the video on page that's listed under RahXephon, which also was listed on someone's blog.
Those lyrics are:
歌を 今風に乗ってI don't know if these are official or not. I also found this version on a Japanese speaker's blog, that they transcribed by ear:
uta wo ima kaze ni notte
haruka tooi anata no moto e
itsuka sora wa hitotsu ni tsunagaru
modotte yukeru anata no moto e
歌う いま風に乗ってThe song can also be heard . What do you guys think?
utau ima kaze ni notte
haruka tooku anata no moto e
itsuka sora mo hitotsu ni tsunagaru
watatte yukeru anata no moto e
