Song Closing the Film

"Song for the Mira" by Allister MacGillivray, written in 1973. There are several recordings of it to be found in YouTube, although some are kind of amateurish.

Ann Murray's, with Celtic Woman, is pretty good:

Unfortunately, the recording that closes the movie -- featuring the three lead actresses (Stacy Smith has a set of pipes!) -- doesn't appear to have been released on its own.
