Dame Cleo Laine, Lady Dankworth DBE (born Clementine Dinah Bullock; 28 October 1927) is an English jazz and pop singer and an actress, known for her scat singing and for her vocal range. Though her natural range is that of a contralto, she is able to produce a G above high C, giving her an overall compass of well over three octaves. Laine is the only female performer to have received Grammy nominations in the jazz, popular and classical music categories. She is the widow of jazz composer and musician Sir John Dankworth.
