Bill Bailey, who died in 1978, was a famous tap dancer, who appeared with Duke Ellington among others, until he decided to give up show business to become a minister. His sister, Pearl Bailey, sang about him in the song, "Bill Bailey, won't you please come home." "Bill Bailey was CJ Edward Craig Jackson's father, and I'm named for his sister," Pernell Bailey said.    C Jay's grandmother, Pernell, is Bill Bailey's widow.
