Well, if there is any link between the Assembly Hall and Abbey Road, it has to be Beatles album "Abbey Road".
All songs from the album are used to show the chronological order of events.
The story goes as the following:
The said person was invited to a meeting at the assembly hall where all witnesses Come Together. He then felt Something hit him over his head. It was Brother Maxwell's Silver Hammer. "Oh Darling!" cried out his wife who saw the incident "You killed him!". Maxwell the said "Let's hide him in the Octopus's Garden!" "IWant You over here now brother!" Maxwell called over to the attendant standing near by. "Here Comes The Sun" said the attendant "We better throw him into the river before we are seen to disposing the body. Because they were in a hurry, the attendant said "Due to You Never Give Me Your Money, I'm going to get Brother Sun King and Mean Mr Mustard". Overseeing this was Sister Polythene Pam where She Came In Through The Bathroom Window whom she caught a brother Sun King having a Golden Slumbers ordered him to Carry That Weight of the of the body to the river. "That's The End to that problem" said Her Majesty.
The "said person" may have been named Paul. See the except below from Wikipedia.

"Paul is dead" clues
The cover also supposedly contains clues adding to the "Paul is dead" phenomenon: Paul is barefoot, with eyes closed, out of step with the others, and holds a cigarette in his right hand, though he is left handed, and the car number plate "LMW 281F" (when read as '28 if') supposedly referred to the fact that McCartney would be 28 years old if he were still alive. (McCartney was actually 27 when the picture was taken). "LMW" is said to stand for "Linda, My Wife," "Linda McCartney, Widow," or "Linda McCartney Weeps".
The four Beatles on the album cover, according to the "Paul is Dead" myth, represent the priest (John, dressed in white), the undertaker (Ringo in a black suit), the corpse (Paul, in a suit but barefoot—like a body in a casket), and the gravedigger (George, in jeans and a denim work shirt).
On the back of the LP cover, there is a series of dots before the word "Beatles", which resemble a "3" when connected. This is a hint at the fact that there are only three Beatles left.
