Mother of All Blind Items Update

Dr. X posts this from his dressing room:

"Which award-winning actress of the past 50 years was really a man? This link brings you up to date. Some good guesses here. Did you get your t-shirt?

"Of the three candidates I originally mentioned, two - Kay Kendall and Judy Holliday - have been eliminated. The third, Alice Brady, hasn't been 'notted', but the hints suggest it isn't her either.

"Which, after reams of research and thousands of comments probably leaves us back at square one. The reveal will be sometime next week."
