Stephen Colbert may be minus one show on Comedy Central right now, but today he turned up on — of all things — a Michigan public-access program called “Only in Monroe,” where he interviewed “a local Michigander who is making a name for himself in the competitive world of music.” (That’s Eminem, a.k.a. Marshall Mathers, for the uneducated.) Watch the duo’s conversation at the 22-minute mark, and stay for the part where Colbert gets Em to sing Bob Seger songs.
