Tony Shalhoub, who’s currently starring in the exceedingly well-reviewed Broadway musical “The Band’s Visit,” used his off night Monday to fulfill a commitment he made a while ago to do a semi-staged reading of Bertolt Brecht’s “Fear and Misery in the Third Reich” with the Commonwealth Shakespeare Company at Babson’s Carling-Sorenson Theater. But it wasn’t easy. Shalhoub spent some of Sunday rehearsing with his wife, Brooke Adams, and Boston actors Karen MacDonald, Johnny Lee Davenport, Obehi Janice, Joel Colodner, Brandon Whitehead, and Deb Martin before returning to the Big Apple to record the cast album of “The Band’s Visit,” and then flying back to Boston for Monday night’s performance at Babson. The crowd included Oscar winner Chris Cooper and his wife, Marianne Leone Cooper, and American Repertory Theater founder Robert Brustein.
