The closest we're getting to seeing the animation from
Enchanted would be images of Queen Narissa in front of the green screen, the prince in front of the green screen, and a ballroom set, from
this site.
But I have more than pictures, friends! You can see a very brief shot of that green scene in a video
here! Just scroll down to the bottom where it says 2006-"Enchanted" Promotion in very light green above a picture of Idina Menzel with some girl in a blue dress. It interviews the actors and reveals some tidbits, even a few bars of the music!
And speaking of hearing some of the music, you can hear some of it in
this clip! Watch the whole thing. It sounds like someone singing, "to live happily ever a-", and it stops. But my conjecture is that Princess Giselle and her new Manhattan boyfriend are on a boat ride listening to music (ala "Kiss the Girl") played by Spanish musicians in sombreros, and then Princess Giselle starts singing to the music.
