Duke Silver is a jazz saxophonist, playing the tenor saxophone, and is the leader of The Duke Silver Trio. He performs at Cozy's Bar in Eagleton, Indiana, on the second Thursday of every month "Duke Silver" is, in fact, the stage name of Ron Swanson, created to maintain personal privacy during Ron's moonlighting as a musician. Duke's fan base appears to consist entirely of middle-aged (and older) women, many of whom attend performances by the Duke Silver Trio and fervently idolize Duke himself.
