The "The Moor cough" is simply Mikael whispering "Melinda".
"The Moor" 's cough actually refers to a story or an interview if my memory is good. It's not about these whispering you are talking about, where the singer can be heard saying "Melinda" and some breathings. It's supposed to be somewhere else in the song, but no one have been able to find it.
Man, you guys are harsh.
Sorry about that, I guess I won't post here anymore, we can even have civilized discussion. You guys are pretty damn immature, hopefully I can find another Opeth message board where everyone is not assholes.
Bye now.
Its kinda hard to pick up but I'm sure thats where its at. If it is and some other people confirm it and put it up on YouTube, don't be an asshole and please credit me for finding it.
