I headbutted the wall as hard as I could but only a small part crumbled off. I don't get the Pink Floyd connection tho.
I have a two disk copy of one of their tours in GB which has been listened to over & over so instead of speculating about the lyrics I copied this info from Wikipedia:
Wikipedia explains: “The Wall”
Plot summary
(last paragraph) This results in a hallucinatory on-stage performance ("The Show Must Go On") where he believes that he is a fascist dictator, and that his concert is a Neo-Nazi rally, at which he sets brownshirt-like men on fans he considers unworthy ("In the Flesh"). He proceeds to attack ethnic minorities ("Run Like Hell"), and then holds a rally in suburban London, symbolizing his descent into insanity ("Waiting for the Worms"). Pink's hallucination then ceases, and he begs for everything to stop ("Stop"). Showing human emotion, he is tormented with guilt and places himself on trial ("The Trial"), his inner judge ordering him to
"tear down the wall", opening Pink to the outside world ("Outside the Wall"). The album turns full circle with its closing words "Isn't this where ...", the first words of the phrase that begins the album, "... we came in?", with a continuation of the melody of the last song hinting at the cyclical nature of Waters' theme.
