I love Bob Cannon's animation, particularly the few cartoons he worked on with Tex Avery and the Fox and Crow UPA shorts. It's quite loose and energetic. His work under Chuck Jones is great, "The Dover Boys" being my favorite. Though it's interesting that as a director the animation is more conservative and organized. I suppose that the emphasis placed on design at UPA was in part to blame. I'm not knocking his UPA shorts, I'm quite fond of them. Well, most of them. "The Oompahs" is boring as hell. Here's a some clips to compare.
Of all the revivals of Tom and Jerry since Hanna and Barbera's original theatricals I have to say that the 1980 "Tom and Jerry Comedy Show" produced by Filmation is hands down the best. You could make the case that the shorts rival HB's MGM classics. The chase scenes look like they could have been animated by Irv Spence himself, they're so good. Enjoy some art from "The Great Mousini" and "Invasion Of The Mouse Snatchers". Fortunately, someone was kind enough to upload the cartoons to youtube.
