As promised, local electro-pop outfit Wild Cub appeared on last night's Late Night With Jimmy Fallon, where they played "Thunder Clatter," the standout single from their newly re-released Youth. The show was a pretty stacked one, also featuring appearances from billionaire-with-a-five-dollar-haircut (and a heart of gold) Bill Gates and Bieber-impersonating rising SNL star Kate McKinnon. But the Cubbies held their own, delivering an energetic rendition of the lush, bubbly, glossy "Thunder Clatter" and eliciting a "That's what I'm talking about, buddy; that was awesome!" from Fallon himself. Give the performance a look above. Cubs win!
