The Kentucky Four
This dance group performed with Orpheus McAdoo's Minstrel and Vaudeville Company in the late 1890s when the company was located in Australia. Its performances were written about in the Freeman newspaper in the U.S.
The dance group members were Katie Carter, a vernacular dance specialist; Muriel Ringold; Amon Davis; and Aaron Taylor (Master Livers). Katie Carter also danced in the South Before the War production. According to J. Malone, author of Steppin on the Blues, p. 60, Carter's buck and wing dancing helped establish the dance form as a major attraction in black shows.
