Dynamite: Sound Effects - The Voices Behind The Scenes
This one is definitly showing my age, but I came across a stack of Dynamite and Hot Dog magazine from my youth and pulled this article which is a charming puff-piece on voice acting in cartoons way back in the 80's. Between brief introductions of Mel Blanc and Casey Kasem there is the talent of Frank Welker who voiced seven of the Transformers (including Megatron), a couple of Muppet Babies, and Uni the Unicorn from (personal favorite) Dungeons and Dragons. Read on for nostalgic doses of Hulk Hogan, Gobots, and Super Friends.
