Kenny Chesney made a surprise appearance Wednesday (Sept. 27) during Pat Green's sold-out show at City Hall, a music venue near downtown Nashville. Chesney joined Green during his encore performance of his hit, "Wave on Wave." At one point, Chesney jokingly took the fiddle and bow from one of Green's musicians and briefly pretended he was going to play it. Green has served as one of Chesney's opening acts at arenas and stadiums. The City Hall show was opened by singer-songwriter Patrick Davis, who wrote Green's upcoming single, "Dixie Lullaby."
