I recently purchased this DVD to get the Walt Disney animated sequence Hot Choc-late Soldiers. In the intro to the sequence it shows the sheet music for the song and just the slightest ghost image of what looks like Mickey Mouses hand appearing to play the piano. However everything else is plain white. You don't see Mickey's body or the piano. Could this actually be the way the movie looked in the theater or has some mistake been made. I'd be curious if anyone had any info about this.
