Narnia's Hide & Seek Extended version

Hello there!

I was checking out videos on youtube when I found this one. The music sounded familiar but I still can't remember where it comes from. I contacted the uploader but never got a response and now the video's gone. Thankfully, I saved the mp3 before that happened so you can all listen to it and help me out! I'd be very grateful as it is such a beautiful piece!

Here's the link to the track: http://www.megaupload.com/?d=F82LAJ7I

I just found another video with the song: http://youtu.be/8k4ZutrlgKg

It is most likely an unreleased song by:

Henry Gregson-Williams which is who did the score for the movie soundtrack. The clip is an extended scene in which the original song used in the theatrical version of the film was replaced with the song heard in the video clip link you posted.
