Strangely enough, both Mama Cass and Keith Moon died in the same London flat that was at the time of both their deaths owned by Harry Nilsson located at Curzon St. in London, England.

On July 29, 1974 Cass died in her sleep at this flat. It had been incorrectly claimed that she had choked to death on a ham sandwich, which apparently came up due to her weight. She had just completed a two-week stint with nightly standing ovations at London’s Palladium, and was feeling great about herself.

Her autopsy reveled that Elliot’s cause of death was a “left-sided heart failure” and “had a heart attack which developed rapidly.”

Keith Moon was a man who lived in the moment.  About a month after the Who released Who Are You, which was their first new album in years, his girlfriend Annette Walter-Lax said that she remembered Keith “taking his usual glass of water and bucket of pills” before falling asleep around 4 am

On September 7, 1978, according to Annette, Moon woke up at 7:30am and told her he was hungry. After clearing his plate, Moon took Heminevrin, a powerful sedative and fell asleep again. But his snoring meant Annette went to sleep on the couch, where she slept until 3:40pm.

After waking up, she went back into the bedroom, where she found Moon lying on his stomach with his left arm hanging over the side of the bed: “I couldn’t hear him breathing. Right there and then I knew something was wrong. I went into a panic.”

The official cause of death was listed on the death certificate as “Clomethiazole (Heminevrin) overdose, self-administered but no evidence of intention. Open verdict.” It was later revealed Moon had 26 undissolved Heminevrin tablets still in his stomach when he died. Keith was just 32 when he died.

Nilsson, was, as you can imagine distraught, he ended up selling the ‘cursed’ flat and moved permanently to Los Angeles.
