Director's Cut ? Dancing with aliens in the end

I saw thie movie in '89 in VHS, and i remember Christopher Walken dancing with the aliens on a funny music somewhere at the end of the movie.

Now i watched this movie again on DVD and was impatient to see this scene again.
But it's not there anymore, and i am sad because it was very important for the greatness of this movie.

Can anyone tell me if the director reedited the movie in order to be more SF-like, "noir" or dark, cutting hilarous or non serious scenes ?

Is this the only version now available ?
