"The National Joins David Letterman's Triumphant Return to 'Late Show'"

The National welcomed David Letterman back to the Late Show with a heartfelt performance of their song "Space Invader" from their new album Laugh Track. Letterman had suggested the band as musical guests for the episode, but initially learned they were on tour. However, they made a special appearance on the show, prompting Letterman to express his gratitude and give a "tip of the hat" to both The National and the Foo Fighters, who bid him farewell from the CBS show in 2015.
