Deep intox do that darkness peering, long I stood there wondering what th solution to this Rebis could possibly be
Mayfair is in Westminster, but I can't work out a reference to My Fair Lady unless Westminster Abbey is known as the Mayfair Lady. If that's the case then the answer is: London Bridge is falling down, my fair (Mayfair) lady. If not ...I'm still befuddled.
@Charlemagne1333 , Look for my answer in a PM. I thought I’d give the others a crack at your excellent rebus.
