Don't these people ever learn not to mess with the Mouse? :)
It appears that Keith Richards "humorous" remarks about "...snorting a mixture of cocaine and the cremated remains of his deceased father... " (eeeewwwww!) doesn't sit well with Disney. While his much-anticipated cameo appearance in the upcoming Pirates movie certainly is generating a lot of publicity (as if the movie needs any more generated publicity as it is), Disney may limit Richards appearance on behalf of the movie.
This may not necessary be a bad thing. I mean, have you SEEN Keith Richards in person and up close? Even with heavy make-up, he could scare any child under the age of 10!
