Betty — real name Bessie Regina Norris — was recently honored on TV One’s “Unsung,” and some called her one of the most underrated singers of her time.

She recorded so many songs, including her 1971 hit, “Clean Up Woman. She was only 18 when the song was originally released, and it turned out to be her biggest song ever.

Other hits included “Let Me Be Your Lovermaker,” “Shoorah Shoorah,” “Tonight is the Night,” “Where is the Love,” and No Pain (No Gain).

She is survived by her four children Aisha, Patrice, Chaka and Asher.

Sending condolences to the family. Rest in peace Ms. Betty Wright.
