 The family barbecue sees Nana Mary s first appearance on the show. Family and friends (except Dan s father and Roseanne s mother) gather at the Connor household for food, drink and singing, and Roseanne s fellow waitress Bonnie (played by Bonnie Sheridan) gets a chance to show what a great singer she really is. Beverley still manages to upset Roseanne and Jackie from the other end of the phone but Nana Mary turns the tables on her.
