Born in Louisville, KY, Sarah A. McLawler was a vocalist, performer, and jazz organist (she played the Hammond B-3 organ). When she was a child her family moved to Chicago, where McLawler learned to play the piano. After her mother's death, McLawler lived with her father in Pittsburgh, PA. They later moved to Indianapolis where McLawler attended high school and sang with the Gene Pope Orchestra. After high school, McLawler attended Fisk University.

She would return to Chicago and played piano in nightclubs and led an all-female combo (McLawler on piano, Lula Roberts on sax, Vi Wilson on bass, and Hetty Roberts on drums). In 1950, McLawler recorded "My whole Life Through" and reportedly "Your Key Won't Fit My Door." However, recent studies of the latter song claim it was recorded in 1950 for Premium Records in Chicago, IL - #857 by Terry Timmons; see note and link on the entry for "Your Key Won't Fit My Door").

McLawler later married Richard Otto, a classical violinist, and together they formed a duo with Otto on violin and McLawler on organ. She helped popularize the jazz organ, which few women were playing. The couple resided in New York, recording such tunes as "Rainbow on the River" and "My Funny Valentine." Richard Otto died in 1979. Sarah A. McLawler died in 2017. She was the daughter of Vol and Lee Y. Tillery McLawler.
