The Ross Sisters
The most flexible, athletic, talented three sisters this planet has ever seen, the Ross Sisters were a trio of American singers and dancers comprising Betsy Ann Ross (1926–1996), Veda Victoria “Vicki” Ross (1927–2002), and Dixie Jewell Ross (1929–1963). Their stage names were Aggie, Maggie, and Elmira, and they hit their peak of popularity in the 1940’s, but you really have to see them in action to believe just how incredible they really were.
