"Slappy's" solo career started in 1951 when Dinah Washington requested him to introduce her act at the Black Hawk in San Francisco. White started out as a chauffeur to the singer, entertaining her with jokes as he drove. When she was late arriving on stage one evening, Washington, worried about the waiting audience, asked White to go on stage and "say something funny" while she prepared for her performance. "Slappy" was such a hit with the patrons, she kept him on as her opening act. He was once also married to Rock and Roll Hall of Fame inductee and blues belter, LaVern Baker (1929-1997).
