Ronnie Spector, the singer who defined the sound of mid-century girl groups as the frontwoman of the Ronettes, has died aged 78. A statement on her website states: Our beloved earth angel, Ronnie, peacefully left this world today after a brief battle with cancer. She was with family and in the arms of her husband, Jonathan. Ronnie lived her life with a twinkle in her eye, a spunky attitude, a wicked sense of humor and a smile on her face. She was filled with love and gratitude. Her joyful sound, playful nature and magical presence will live on in all who knew, heard or saw her.
