The narrator was definitely Hal Peary, the voice of the title character of the old radio comedy show "The Great Gildersleeve." (The character was originally a "regular" on another classic radio comedy program, "Fibber McGee and Molly.") Notice that even though the Queen already knows that the little man's name is Rumplestilskin, she teases him by pretending to ask if he goes by other names, and one of them happens to be "Throckmorton," which was Gildersleeve's first name, Throckmorton P. Gildersleeve! (I don't think it was ever mentioned what the "P" stood for.) Notice also that Rumpelstiltskin dismisses the idea of his name being "Throckmorton" as "ridiculous." All these were obviously inside jokes. They even threw in Gildersleeve's weird chuckle.
