[Watch] The National - "Don't Swallow the Cap" Live on Letterman

This week saw The National release their fantastic new album Trouble Will Find Me and what better way to celebrate than with a visit to the Ed Sullivan theater and an appearance on The Late Show with David Letterman. The band delivered a stunning rendition of "Don’t Swallow the Cap" complete with strings that will make the hairs on the back of your neck stand up to attention.
