Stephen Colbert appeared on The Howard Stern Show today, where he discussed his little-known musical past. Apparently when he was in high school, the future Late Show host used to front a Rolling Stones cover band called A Shot In The Dark (“We called ourselves ‘A Shit In The Dark,’ cause we sucked so badly,” he says). Colbert revealed that his go-to Stones song was “Brown Sugar” and sang a bit of it for Howard Stern, also busting out some excellent Mick Jagger dance moves. Watch below.
