Marva Whitney (born Marva Ann Manning; May 1, 1944 – December 22, 2012) was an American funk singer commonly referred to by her honorary title, Soul Sister #1. Whitney was considered by many funk enthusiasts to be one of the "rawest" and "brassiest" music divas. Biography Early life Born in Kansas City, Kansas, her performing career started as early as three years old while touring with her family's gospel group, the Manning Gospel Singers. At the age of 16 she joined the Alma Whitney Singers and two years later she married Harry Olander Whitney with whom she had a daughter Sherrie Whitney. She began singing R&B music for the first time in 1963 at a Kansas City venue and studied music at college. Whilst working at a garment factory, she continued performing in nightclubs and at local talent competitions, and by the mid-1960s had joined local group Tommy (Gadson) & The Derbys as their lead singer. The group opened for many leading performers passing through Kansas City. In 1967, she left the group, and turned down offers to tour with Bobby Bland and Little Richard before joining the James Brown Revue as a featured vocalist. Her marriage to Harry Olander Whitney ended in divorce in 1965. Subsequently, she was married, albeit briefly to disc jockey Phil Wardell. Career Her first solo single, "Your Love Was Good To Me", was recorded for King Records in mid-1967, but was unsuccessful as were two follow-up singles. She toured Europe, Asia and Africa with James Brown with whom she was in a relationship, and in early 1968 he produced her fourth solo single, "Unwind Yourself", in a more funky style. Although the record was not a chart hit, it was later sampled numerous times, most recognisably by the 45 King on his 1987 track "The 900 Number", which was then sampled by DJ Chad Jackson on his 1990 hit single "Hear the Drummer (Get Wicked)" (UK number 3 in July 1990), by DJ Kool on his 1996 hit "Let Me Clear My Throat" (UK number 6 in March 1997), Sway on his 2009 track "Mercedes Benz" and Mac Miller on his 2011 track "Party on Fifth Ave." Whitney's first chart hit came with "It's My Thing (You Can't Tell Me Who to Sock It To)," a response to The Isley Brothers' hit "It's Your Thing"; her record reached number 19 on the Billboard R&B
