Following a recap of skiing techniques – seriously Dave, you’ve never been to Vail? – Donald Glover, aka Childish Gambino, gunned through a performance of Camp favorite “Heartbeat” last night on The Late Show with David Letterman.

Admittedly, it’s hard to grasp any edge when Glover’s wearing a cribbed Santa sweater, but hey, lyrics are lyrics, right? He’s on fire here, and if you recently snatched tickets to his Camp Gambino shindig, then you’re in for a fiery night – at least if this is any indication.
