And depending on how crazy you want to make yourself, "Tom and Jerry's Greatest Chases Vol. 3" is (to the best of my knowledge, everyone correct me if this is out of date) the only U.S released DVD version of "Touché, Pussy Cat!" that includes as an audio option the original MONO mix containing the little mouse singing "Frere Jacques", the song that somehow didn't make it into the stereo version on the Spotlight DVD's. His voice was accidentally omitted in the stereo mix, and you just hear the background music while he's painting.
The Spotlight disc only has the stereo mix, the Greatest Chases 3 gives you both.
