The Rutles' All You Need Is Cash Clues

In 1978, Eric Idle (of Monte Python's Flying Circus comedy group) and Neil Innes (of Monte Python and Bonzo Dog Doo-Dah Band satirical groups) wrote and starred in a satire about The Beatles called All You Need Is Cash.  They covered the Paul Is Dead story with a  mixture of George, Paul and replacement Paul references.

In the video on YouTube:  www.youtube.com/watch?v=g6PgzRizr6o  they cover the rumor that Stig--the George character--might have died.  At 0:06-0:16 in the video, the commentator (Eric Idle) says,
       "Stig had hidden in the background so much that a rumor went around in 1969 that he was dead.  He was supposed to have been killed in a flash fire at a water bed shop and replaced by a plastic and wax replica from Madame Tussauds."  My interpretation of this is that they were alluding to:  the Lotus hyperbaric chamber bed I've mentioned in previous posts; and to the man who replaced Paul who needed plastic surgery to resemble Paul enough to convince a world audience.

The movie talked about the Paul Is Dead clues.  Beginning at 0:27-0:30, they say :
      ". . . he'd not said a word since 1966."
At 1:30-1:38 (in a reference to, apparently, Linda Eastman, who married the man who replaced Paul):
      "He'd fallen in bed with Gertrude Strange . . . whose father had invented the Limpet mine." 
 Limpet mines were naval mines developed in England during World War II that were attached by frogmen (underwater divers) to enemy ships.  Again, I think this was an inside joke about Paul and the hyperbaric oxygen chamber.
