uhh.. i checked out yuuri's voice..

i think this is what he said at the last part...

though i think some parts are off..

Yuuri: kono sekai ni zutto nantte naite wakatteru
dakara kuso yakusoku wo kawaseru naa
matta otte yubiki shirou
soshite wa hora kokoro na anata ka gakou na ni naru kuna ru
tsunagatte iru tte sou shinjirareru hazu daa
daijobu zutto ga nankereba zutto hanareba tte kuto mo nai saa
itsuka matta ai ru egao de sai kai shioi yo
sou to kinou ore mou me ippai ne egao de minna ni yu yo
tadaima tte

oh my gawd i so love yuuri!!!

*squeel* is that wolfram singing the first part
his voice is so cool *squeel*
and the song is so cool
i really luv it

So. Here's my shot at the whole "who sings where" mystery. But, do note that these are just...well, let's say...educated guesses, perhaps? Yeah. Here we go:

Lyrics from the awesometastic people at http://bllyrics.gratis-board.de/bllyrics-beitrag28.html

[Wolfram:] Negai ga kanau nara dokomade mo soba ni itai yo
[Conrad:] Mitsumeawanakute mo onaji mono wo, itsumo mite iyou

[Gunter:] Ima ha ienai kedo utaenai kedo
[Anissina:] Itsuka mata, au hi ga kuru kara

[Gunter/Anissina:] Jaa ne kondo ne mijikai yakusoku
[Gunter:] Hitotsu hitotsu dakishimeteta
[Wolfram/Conrad:] Ai no kuuki ga mune ni shimita
[Gwendal:] Kokoro, atatameatte boku tachi ha ikite iru

[Murata:] Chiisa na shinsetsu ga ureshisa no tane maite iku
[Cheri:] Sukoshi zutsu hirogatte ureshisugiru mori ni tsutsumareru!

[Yosak:] Niteru hito ni aeta sore dake de mou
[Shouri:] Kono machi mo hito mo suki ni naru

[Wolfram/Murata:] Mata ne zutto ne hakanai yakusoku
[Shouri(/Gunter? I hear him everywhere, I swear.):] Dakara sore wo, daiji ni shita
[Murata/Gunter:] Shinjiru dake de tsuyoku nareru
Ai no kuuki, sutte boku tachi ha ikite iru

[Conrad/Wolfram:] Asu to kibou to heiwa to shiawase chotto mitsuketa toki
[Gwendal/Anissina:] Saisho ni tsutaetai to ukabu no ga, suki na hito na no sa

[Wolfram/Cheri/Anissina:] Jaa ne kondo ne mijikai yakusoku
[Conrad/Gwendal:] Hitotsu hitotsu [Conrad:] dakishimeteta
[Murata/Conrad/Gwendal/Shori(/probably all of the guys, but I distinctly hear four voices, so...:]
Ai no kuuki ga mune ni shimita
Kokoro, atatameatte soba ni ikou

Mata ne zutto ne hakanai yakusoku
Dakara sore wo, [Murata:] daiji ni shita
[All guys:] Shinjiru dake de tsuyoku nareru
Ai no kuuki, sutte
Boku tachi ha [Gwendal/Anissina:] yasashiku [Conrad/Wolfram/Gunter/Shori:] shibutoku
[All guys:] ikite iku

[Yuuri's dialogue]

[Everyone in the background]
Sekaijuu de hora yakusoku, kawashiteru
Mayowanaide mou koko he oide saa

I could only hear Yosak once, so... O_o

But I personally hear Wolfram singing in...everything. XD Well, I'm pretty sure he sings the first part, and I could make out a couple more parts where he duets with Murata and Conrad...and then it gets harder with the last two stanzas when three or more people start singing.

Hope it helps.

*wonders*Is Wolfram's voice that "invisible'?

does someone have the lyrics?

I REALLY like this song!

O_O lol. it was Wolfram that sang the first lyrics >

can you send this song to me~>

Wolfram-sama sings first in the whole song
