Ellen Naomi Cohen (September 19, 1941 – July 29, 1974 Baltimore, MD), known professionally as Cass Elliot, was an American singer. She was also known as “Mama Cass“, a name she reportedly disliked. Elliot was a member of the singing group the Mamas & the Papas. After the group broke up, she released five solo albums. Elliot received the Grammy Award for Best Contemporary (R&R) Performance for “Monday, Monday” (1967). In 1998, she was posthumously inducted into the Rock and Roll Hall of Fame for her work with the Mamas & the Papas.

Elliot left that party at 8:00 p.m. on Sunday, July 28 1973 , saying she was tired and needed to get some sleep.

Elliot retired to an apartment in Mayfair at Flat 12, 9 Curzon Place (later Curzon Square), Shepherd Market, Mayfair, London, owned by singer-songwriter Harry Nilsson who allowed her to stay there. Several hours after Elliot left Jack Martin’s cocktail party, she died in her sleep at age 32. Her body was discovered by a close friend of hers who went to check on her. According to Keith Simpson, who conducted her autopsy, she died of a heart attack, and there were no drugs in her system. Four years later, Keith Moon, drummer for The Who, died in the same bedroom, also aged 32 years.
