Apparently the last of the founding sisters in 1969, after June (died 2006) and Bonnie (died 2020). Younger sisters Bonnie and June started as a duo, then older sister Anita joined officially becoming The Pointer Sisters. They became a quartet when oldest sister Ruth joined in 1972. In 1977, Bonnie struck out to be a solo act, and June temporarily took a break. June was back when they had their big 80s hits (which is where I was introduced to them). Remaining sister Ruth still tours as the Pointer Sister with one of her daughters, Issa, and one of her granddaughters, Sadako.
