Chicago-based band The Orwells performed an encore song on Letterman back on June 10th, now released as a web-only bonus track. Watch above.
This being their second appearance on Late Show, Letterman had already expressed how much of a fan he is, begging them the first time to play an encore song. This time they delivered.
We get more of singer Mario Cuomo's slightly deranged gaze and some added vocals from Letterman's sidekick, Paul Shaffer. The final surprise is Cuomo sticking the mic down his pants.
