Music search: cello piece in "Unending"

[sulien.livejournal.com]

This is a request to ask what the cello piece was that Sam played in the SG-1 finale, "Unending".  I've Googled it every way I can think of and looked on several 'Gate sites, but have had absolutely no luck finding any information.  Can anyone tell me what it was so that I can track down a CD with it, or was this one of Joel Goldsmith's compositions just for the series?  Help?  Pretty please?  :-/

Edited to add: answer found by captain_tibbs .  The piece is one composed by Joel Goldsmith to match the bowing and fingering of the cellist hired to double Sam in that particular scene.  Hopefully the piece will make it onto a compilation soundtrack CD one of these years!
