Nípa Cass
Ellen Naomi Cohen (September 19, 1941 – July 29, 1974), known professionally by the stage name Cass Elliot, was an American singer-songwriter, actress, comedian, and television personality. A member of the singing group The Mamas & the Papas (1965–1968), she was also known as "Mama Cass", a name she stated she disliked. After the group broke up, Elliot released five solo albums. She 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. — Source: Wikipedia
