Man! He was one of the voices of my childhood! When I started watching M*A*S*H and he came on as Charles to replace Frank, not only did I recognize the name almost immediately, but the pompous voice and Boston accent he used for Charles was very, very similar to Cogsworth's stuffy, upper crust voice and accent as well.
And has anyone noticed that many of the Disney characters he's voiced have shared a lot of his physicalities?
