trust me, U will LOVE this video, LOL; i have tears in my eyes, both from laughing and how amazingly sweet it is - the editing is =Phenomenal=.
it really does look as if they are singing - the lip-synch [and beak-synch] is terrific! thanks so much to the person who created this clip, the "stars" who appear in it, and their loving families - it's wonderful.
