The Best in Show winner at the Westminster Kennel Club Dog Show is heading to Broadway. Not to see a show — to be in one. The Roundabout Theatre Company said Banana Joe, the 5-year-old affenpinscher who emerged triumphant Tuesday at America's premier dog competition, will appear for one night only in "The Mystery of Edwin Drood" on Wednesday. The dog will replace Macaco, the 5-year old Maltese-Yorkie mix that is the real-life pet of actress Stephanie J. Block.
