It seems like the Tom and Jerry: The Movie commercials barely showed any scenes with them talking. I remember once seeing a commercial with a clip from the "Friends to the End" song and thought, "Is Tom talking in that scene?", but still didn't think much about it until I finally saw the movie. One of my friends rented it, and told me that they talked before I watched it, leading me to think, "Oh, so that was Tom talking in that commercial!"
And am I the only one who thinks the "Friends to the End" song sounds very similar to "Together Again" from The Muppets Take Manhattan?
