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.
