Hmm........maybe,.......always heard she choked on a bite of ham sandwich.........could google it, but that would be kinda creepy ...........
We are both wrong, but you got the rumour right. In Canada, it was a chicken bone, but we were far from the source, There was a ham sandwich on her bedside table. Interesting, because she was Jewish, which I didn't know. I guess she wasn't kosher.
Here is my source, but several other sites, including a Jewish site, said the same thing.
"In 1974, Cass was in London where she was performing at the London Palladium to sold-out crowds. On the evening of July 29, 1974, after giving a spectacular performance, Cass tragically was the victim of a heart attack, which ended her life at the young age of 32. Many rumors circulated regarding her untimely death. These included a drug overdose, an FBI assassination plot, that she was pregnant with John Lennon’s child, and suicide. The most popular and resilient of these rumors was that she had choked to death while eating a ham sandwich.
The ham sandwich myth was fueled by the report of Dr. Anthony Greenburgh, the physician who first examined Cass after her death. Greenburgh reportedly told the
Daily Express that “she appeared to have been eating a ham sandwich and drinking Coca-Cola while lying down—a very dangerous thing to do,” and continued, “she seemed to have choked on a ham sandwich.” He came to these conclusions from his first impression upon entering the scene, and he believed she died of asphyxia. Dr. Greenburgh completely overlooked the fact that the ham sandwich sitting on the table had not been touched.
The facts about Cass Elliot’s death were documented shortly after she died by Keith Simpson, one of Great Britain’s leading forensic pathologists at that time. The forensic autopsy showed there was “a heart problem leading to heart failure; there was no sandwich or any other item lodged in her throat or trachea; and she had had very little to eat the day before she died.” A routine drug screening showed no drugs were in her system. The cause of death was “heart failure due to fatty myocardial degeneration due to obesity.” That conclusion was controversial and disputed by American pathologists at that time. The theory exists that Cass had a cardiac conduction deficit. She frequently suffered fainting episodes that went unexplained."
