London dance-rock kings Hot Chip made their way to Late Night With Jimmy Fallon last night to serve as the program's musical guest. And with a little help from The Roots' Questlove, the five-piece performed '80s-tinged In Our Heads jam "Don't Deny Your Heart." If you're feeling a little down or reaching for a second (or third) cup of coffee this morning, let this be a warm dose of caffeine for your ears.
