Clip- Female Singing

I thought this was a very interesting audio clip and just had to put it up here. There are so many things going on that I don't think I even caught them all. I am putting up both the original file and then the file I ran through noise reduction. You hear a very strange noise in the beginning of the clip but, then you begin to hear a woman singing. Shortly after she starts singing John asks if there is a woman in the room. I don't know why he asks, maybe he felt a female presence. But, this woman continues to sing. Eventually it fades out but, other voices can be heard as well. It's quite a menagerie of voices.
