Jay and Mark Duplass recently showed up on Conan to promote their HBO show, Togetherness. Fans of the dramedy will remember a pivotal scene where Mark and Steve Zissis do a masterful air-drum solo to Rush‘s “Tom Sawyer,” a bit that, according to them, comes directly from the Duplass brothers’ own lives. (“Tom Sawyer” is proving to be a popular cover song these days, no?) Describing their air-drum solo past to O’Brien, the three promptly stood up to reenact their (frankly, pretty spectacular) Neil Peart impression. Watch it above.
