The Raven Actually Had Two Voices
Bob Hastings was an American radio, television, film character actor, as well as a known voice in animated cartoons. He is most known for his portrayal of Elroy Carpenter on McHale’s Navy.
However, another voice he did was fill in for Mel Blanc as the voice of The Raven when Blanc was too busy with his various voice acting gigs. We can’t blame him though since we would rather be voicing Bugs Bunny over a bird that pops out of a clock for a few seconds per episode.
