Tiny Topsy, born Otha Lee Moore, was an American R&B singer active during the late 1950s. Known for her powerful contralto voice and energetic performances, she was one of the few female artists in the largely male-dominated Chicago blues scene. Despite her raw talent, Topsy's career was short-lived, releasing only a handful of singles, with "Just A Little Bit" becoming her most recognized song. While she may not have achieved widespread fame during her lifetime, her contributions to R&B and blues have been recognized posthumously, making her a notable figure in the history of these genres.
