Schiller - Beautiful Day

Does anyone know if Schiller made up and had someone sing the opera part in his song Beautiful Day or if he sampled it from something...like Puccini - Madame Butterfly?

He is a trance producer, so I apologize if this isn't appropriate for this forum, but it's killing me since I can't find it online at all anywhere else...

Plus the fact that I sampled it and want to give appropriate credit on my c.d. =)

If you go to about 51-52 seconds in, the woman starts singing the opera part I'm referring to. I believe it is sung by a woman named "Isgaard". Is this influenced at all, and does anyone know what it means?

beautiful track man... but sounds to me he had someone redo it cause i have Madame Butterfly i cant remeber one record that i have but the other one is done by malcolm mclearn and it dont sound like that.
