From the Wiki
Helen Humes (June 23, 1913 – September 9, 1981) was an American jazz and blues singer.
Humes was successively a teenaged blues singer, band vocalist with Count Basie, saucy R&B diva and a mature interpreter of the classy popular song.
Born in Louisville in 1913, Humes got her gift of song from her parents, who often performed duets together at church and social functions.
Humes was born in Louisville, Kentucky,  was spotted by the guitarist Sylvester Weaver and made her first gramophone records in 1927, her true young voice consorting oddly with bizarre material like “Garlic Blues”.
She moved to New York City in 1937 and became a recording vocalist with Harry James’ big band. Her swing recordings with James included “Jubilee”, “I Can Dream Can’t I”, “That’s the Dreamer in Me” and “Song of the Wanderer”.
Humes became one of the vocalists with the Count Basie Orchestra in 1938, replacing Billie Holliday as lead female vocalist. Her vocals with Basie’s band included “Between the Devil and the Deep Blue Sea”.
By 1937 her aspirations to perform had taken her as far away as Albany, New York. While performing with the Al Sears band at the Cotton Club in Cincinnati, Helen Humes was spotted by “The King of Swing,” Count Basie. He invited her to replace Billie Holiday and join his band as a singer, but she declined because she didn’t want to venture too far from home. The following year, Count Basie again invited her to join his band, and this time she accepted.
During the 1940s and 1950s, Humes became a solo performer and worked with different bands and other vocalists including Nat King Cole. She sounded very sprightly on the jump blues Be-Baba-Leba (Philo, 1945) and Million Dollar Secret (Modern, 1950).
In 1950 Humes recorded Benny Carter’s “Rock Me to Sleep”. She managed to bridge the gap between big band jazz swing and rhythm and blues. She appeared on the bill at the Monterey Jazz Festival in 1960. Her vocal styling is reminiscent of Dinah Washington.
She moved to Hawaii and then to Australia in 1964, returning to the US in 1967 to take care of her ailing mother. Upon her mother’s death in 1973, Humes sold her records and piano and resolved never to sing again. In 1973, music critic Stanley Dance asked her to appear with Count Basie at the Newport Jazz Festival. With her father’s consent, she went.
She made a full comeback and stayed busy up until her death, performing all over Europe, for instance, including at the prestigious Nice Jazz Festival in the mid-70s. She received the Music Industry of France Award in 1973, and the key to the city of Louisville in 1975.
Helen Humes died of cancer at the age of 68 in Santa Monica, California. She is buried at the Inglewood Park Cemetery, Inglewood, California.
