HA!!! Found him...
In 1945 Detroit’s Frank “Sugar Chile” Robinson lost a boogie woogie piano contest because he was too young to officially compete; he was six years old. By the age of eight he had performed with Lionel Hampton, played for President Truman at the White House, and appeared in the Hollywood movie “No Leave, No Love” with Van Johnson and Keenan Wynn. By the age of 12 he was one of the most famous entertainers in the country, regularly breaking box office records at theatres across the country and in Europe.
By the age of 15 Sugar Chile had all but disappeared and for the past 50 years music historians and boogie woogie affecionados have been asking, "Whatever happened to Sugar Chile?"
