This is odd, but it's exactly one year later, I'm just surfing and I've hit upon this thread and the fact that my pal Paul Pain agrees with the contention, first posited by me and more-or-less seconded by Green Canaries that The Mayor and Mr McGurn are not the same actor. Thank you, Pain old man, we're up against some Hollywood Heavyweights on this, perhaps in time we'll all engage and reach the truth.
In the meanwhile, how about my contention that the unshaven Effie the Bearded Lady, and the shaven Effie, are not the same actor/actress? I can entertain the theory that the unshaven Effie is an actual bearded lady, or at least a woman, due to her theatrical but womanly voice, while the shaven Effie is a man. The two really don't look alike, and the one with the beard comes across as more womanly than the one without. These are deep waters, indeed.
