Jason Fraley interviews five-time Grammy winner Mary Chapin Carpenter, who performs at Wolf Trap in Vienna, Virginia this Saturday. They discuss her earliest open-mic nights in Washington D.C., how The Birchmere helped her get signed by Nashville and how a Bethesda dance club inspired her song “Down at the Twist & Shout,” kicking off a string of country hits like “I Feel Lucky,” “Passionate Kisses” and “He Thinks He’ll Keep Her.” (Theme Music: Scott Buckley’s “Clarion”)
