The lyrics to "The World Without Logos," the Hellsing opening song. It's not really in any language, but if one were to be picked, it would be English.
Official Lyrics, from Hellsing OST 1, Raid
Don't be cool vibration Revolufantasy Tell me fool talk show day and rain

Lyrics from the Hellsing fansub
Tell me (the) cool vibration Liv(ing) your fantasy Tell me who, tell me surely, and the name
I'll be stunned, I'll be waiting ghosts (of) horror show In a darken just say you love
(Ah) Down, down wish its just a revelation Take me there, take me into a revolution
Down, down, listen to the vibration Take me home and I'll look into return
OR
Tell me cool vibration Live your fantasy Tell me who, tell me surely, and the name
I'll be stunned, all be waiting ghosts of horror show And I don't care just say you love
Ah Down, down, won't you stay the night show? Take me one, take me into a revolution
Down, down, won't you hear the vibration Take me home and call me gold
...Yeah, still pretty cryptic. But hopefully a *little* easier to follow.
