"Brain Damage (J Floyd K Remix)" by the National Cynical Network comes from an album dedicated to JFK-related recordings called Puzzling Evidence - The JFK Show (2011). NCN take an acoustic version of Pink Floyd's "Brain Damage" and transform it into a conspiracy theory sound collage. Forget about The Dark Side of the Moon being a soundtrack for The Wizard of Oz, in NCN's hands Pink Floyd's 1973 album is about the JFK assassination!

Many of the samples used in "Brain Damage (J Floyd K Remix)" come from the documentary The Men Who Killed Kennedy, originally produced by ITV in the UK in 1988. This documentary, which argued that a conspiracy had taken place in the JFK assassination, included many interviews with eyewitnesses to the assassination and others involved in the subsequent investigation. Each sample relates to the lyrics or the theme of "Brain Damage" in some way and the lyrics take on new meaning in this light. Mary E. Woodward, reporter for the Dallas Morning News, was in Dealey Plaza on November 22, 1963, and submitted her report that day stating that she heard shots coming from the grassy knoll--followed by the lyric "The lunatic is on the grass". We then hear accused assassin Lee Harvey Oswald make reference to newspaper reporters in the hall--echoed by the lyric "The lunatic is in the hall". Paul O'Connor, a laboratory technologist who assisted with JFK's autopsy, suggests that shadowy figures interfered with the autopsy, and Cyril Wecht, a forensic pathologist who participated in the House Select Committee of Assassinations (HCSA) re-examination of the JFK assassination in the late 1970s, asserts that JFK's brain was tampered with ("Brain Damage") to support the explanation that only one person assassinated JFK. The "lone nut" theory is disputed by James Tague, who was wounded by a bullet as he watched JFK's motorcade, and Robert Groden, a photo-optics technician who served as a consultant for the HCSA, who testified that the autopsy photos of JFK's brain had been faked.

Though Ron Jenkins, reporter for Dallas radio station KBOX in 1963, was referring to the assassination when he reported, "Something is wrong here. Something is terribly wrong." in this track his words come to mean the sinister plot behind the assassination by people who had the ability to tamper with the evidence. The track concludes with a quote by J. Gary Shaw, former director of the JFK Assassination Information Center in Dallas and the Assassination Archives and Research Center in Washington, DC. "If they lied to us, how much are they lying to us in other areas? And if they're lying to us, can they do it again and again and again? If so, this is not a democracy. It's a hierarchy--a government or people run by certain powerful individuals who have the ability to dispose of anyone not going along with the party lines, so to speak.... The truth is the most important thing."
