Celine Dion - The Show Must Go On Comparison

Here's a comparison between two videos (available on KZbin) from Celine Dion singing "The Show Must Go On", easily placed side by side in two windows, and played at the same time.
Notice how the "Le Spectacle" version, that should've been shot in Montreal, is a 'collage' using footages from "The Concert", recorded in Boston.
The same happens with ALL other English tracks of the "Le Spectacle" DVD.
Enjoy! ;)
Obs: I do not own the rights of the video.
