He will always be the voice of Space Ghost but when I was old enough to get up for Saturday-morning cartoons (never on school days!), he was also the voice of Blue Falcon, the Batman-knockoff for Scooby-Doo. My parents recognized him more for Laugh-In. I do recall him doing some Sesame Street bits. Lastly, he did have a minor comeback in Ren & Stimpy as Powdered Toast Man.
What I didn’t know until I read his obituary, Gary was a writer for the various Jay Ward cartoons: Rocky & Bullwinkle mostly. Too bad he didn’t do any memorable voices, most characters were the grande dame June Foray and veteran Paul Frees.
Gary will be missed. He had a very distinctive voice alongside all the other legends who have passed on: Mel Blanc, Paul Frees, Christine Cavanaugh and Daws Butler.
