Josh Groban to visit 'The Office'

Here’s some interesting casting:

Singer Josh Groban will make a guest appearance on the upcoming eighth season of “The Office” playing the brother of Andy Bernard (Ed Helms).

As we all know, Andy is an  a cappella warbler of some renown, so one can only speculate whether they’ll perform a duet.

Groban will be in an episode about Andy's family coming to Scranton for a visit. Their parents will be played by Stephen Collins (“7th Heaven”) and  Dee Wallace (“E.T.”).
