This day in music history.

July 29, 1974, Mama Cass Elliot ( member of the Mama's & Papa's) dies in London. A postmortem the following day shows she died as a result of choking on a sandwich and from inhaling her own vomit. It's later revealed that she suffered a heart attack. She was 32. Her last words were "Goddamn it! They forgot the fucking Mayo again!"
