The correct answer is Bobby Troup!
Bobby Troup is not strictly a jazz performer but he has made several important contributions to the music. As a composer he has written “Daddy,” “Snooty Little Cutie,” “Baby, Baby All the Time,” and the major hit “Route 66.” Troup has long been a fine pianist (having a regular jazz trio in the 1950s), a personable singer (although some of his early records were overly mannered), and an actor, and during 1956-1958 he moderated a legendary television series (Stars of Jazz) that featured a who’s who of jazz players. He also produced some best-selling records for his wife, Julie London.
