Question: What type of business did Jimmy Duncan's father own when Jimmy was going to the University of Tennessee? Passage:Duncan was born in Lebanon, Tennessee. His "paternal grandparents were small-areage farmers in Scott County, which in 1861 left Tennessee, refusing to follow the Volunteer State into the Confederacy, and declared itself 'the Free and Independent state of Scott.'" Duncan's parents were Lois (Swisher) and John Duncan Sr., who "hitchhiked into Knoxville with five dollars in his pocket,' and after an education at the University of Tennessee was elected mayor of Knoxville and then congressman." The elder Duncan was also a co-owner of the Knoxville Smokies of the "Sally League," for which his son "was a batboy, a ball shagger, scoreboard operator, and, as a freshman at the University of Tennessee, the Smokies' public-address announcer." Duncan also worked as a grocery bagger and salesman at Sears while working his way through school. Duncan supported Barry Goldwater's 1964 presidential campaign, and sent the first paycheck he earned as a bagboy at the local A&P to the Goldwater campaign.
