"The Office" star Ed Helms portrays a regional sales director in the pseudo-documentary known for his pompous attitude and penchant for occasional musical interludes. The latter came through on Friday, as Helms joined Old Crow Medicine Show to provide vocal and banjo accompaniment during their Michigan Theater performance. Helms, along with "Saturday Night Live" actor/writer Seth Meyers (who also attended the Old Crow show), Anne Heche and John C. Reilly, is in town filming "Cedar Rapids."

For the full rundown of the night, check out Will Stewart's review of the Old Crow Medicine Show concert.
