Oh that Josh Groban.  Always willing to poke a bit of fun at himself, always leaving us with a song in our hearts.  After his most recent turn helping Jimmy Kimmel eulogize himself in memoriam at the 2012 Emmys, and rather than return to his occasional 'Glee' guest spot, the piano crooner is setting his sights on a return to the final season of NBC's 'The Office!'  Reprising his role as Andy Bernard's younger brother Walter Jr., fans are going to find something different about Groban's appearance this time however...

Many familiar faces are likely to breeze through 'The Office' for its final season, but for now one of the first reprisals is that of singer Josh Groban, playing Andy Bernard's (Ed Helms) younger brother Walter Jr.  First reported by TVGuide, Groban's return appearance won't be exactly as viewers remember him from last season's "Garden Party," as the youngest Bernard seems to have fallen on hard enough times to become a washed-up alcoholic!

Groban will appear in the November 1st episode, entitled simply "The Boat."  Apart from early season star, Groban is the first re-appearance for the show's final season, which will also boast Stephen Colbert in its Halloween episode.

What say you?  Are you hoping more 'The Office' guest stars will pop up for the final season?  Who do you miss the most?
