Roy Kral (October 10, 1921 – August 2, 2002) was an American jazz pianist, arranger, and vocalist.
Particularly successful for the band were arrangements by Kral of the jazz standards "Flamingo" and "Pennies from Heaven".
The couple left Ventura's band shortly before their marriage in June 1949, and afterwards performed briefly as a part of a bop sextet organized by Kral.
In 1953 they returned to Ventura's band for an eighth month period, and then after were active as performers in New York and Los Angeles in the mid 1950s.
The singer Anita O’Day temporarily replaced Jackie as part of the duo on periodic occasions in the 1950s during the births of the couple's two daughters.
