Relient K played a free show at Nashville diner over the weekend. They also debuted the new song “Over My Head.”

They ran through a stacked setlist: Classics like “Be My Escape,” “Who I Am Hates Who I’ve Been,” “Sadie Hawkins Dance,” “High of 75,” and “Chap Stick, Chapped Lips, and Things Like Chemistry” were all there. But they also surprised diehards with deeper cuts like the rarely performed “Jefferson Aero Plane” and a warm, lingering closer: “Savannah.”
