Glee's Defying Gravity

Updated 6 Aug 2010: Changed Youtube link as it was removed by Sony. This Duet is not as good as the one I heard.
Updated 2 Sep 2010:  Added another Defying Gravity's video link

Just watched Glee and I think that this song, Defying Gravity is amazing. When I saw both Kurt and Rachel singing, I was thinking how well they sang together. Imagine my surprise when I heard this in Youtube. The song is amazing, but surprisingly short.

Enjoy.
