Keith John Moon (23 August 1946 – 7 September 1978)

Murder. After moving in, Moon began a prescribed course of Heminevrin (clomethiazole, a sedative) to alleviate his alcohol withdrawal symptoms. He wanted to get sober, but due to his fear of psychiatric hospitals he wanted to do it at home. Clomethiazole is discouraged for unsupervised detoxification because of its addictive potential, its tendency to induce tolerance and its risk of death when mixed with alcohol. The pills were prescribed by Geoffrey Dymond, a physician who was unaware of Moon's lifestyle. Dymond prescribed a bottle of 100 pills, instructing him to take one pill when he felt a craving for alcohol but not more than three pills per day.
By September 1978 Moon was having difficulty playing the drums, according to roadie Dave "Cy" Langston. After seeing Moon in the studio trying to overdub drums for The Kids Are Alright, he said: "After two or three hours, he got more and more sluggish, he could barely hold a drum stick." On 6 September Moon and Walter-Lax were guests of Paul and Linda McCartney at a preview of the film, The Buddy Holly Story. After dining with the McCartneys at Peppermint Park in Covent Garden, Moon and Walter-Lax returned to their flat. He watched a film (The Abominable Dr. Phibes), and asked Walter-Lax to cook him steak and eggs. When she objected, Moon replied "If you don't like it, you can f* off!" These were his last words. Moon then took 32 clomethiazole tablets. When Walter-Lax checked on him the following afternoon, she discovered he was dead.
