Peggy Jones (later Malone, July 19, 1940 – September 16, 2015), known on stage as Lady Bo in recognition of her relationship with Bo Diddley, was an American musician. A pioneer of rock and roll, Jones played rhythm guitar in Bo Diddley's band in the late 1950s and early 1960s, becoming one of the first (perhaps the first) female rock guitarists in a highly visible rock band, and was sometimes called the Queen Mother of Guitar.
