Ann is on a short list of two for a television commercial for Pop, a new soft drink. Mr. McKorkle, the Pop representative, really believes Ann is the better choice of the two actresses, however the person chosen is required to sing, which Ann can't do very well as witnessed in her call-back audition. That's when Mr. McKorkle gets the brilliant idea to have Ann lip-sync the song for the commercial. During the filming, Ann meets her "voice", a beautiful young woman named Rose Cassanetti. Rose is represented by her musician brother, Tony Cassanetti, who gets her the odd singing job here and there. Ann believes Rose could go so much further in show business if she only had the right connections and a bit more drive in achieving show business success as a goal, which she doesn't seem to have. Ann is determined to help her, especially in getting her own agent, Seymour, to hear her sing and represent her. Donald believes Ann's meddling isn't such a good idea, at least not until Ann clears ... Written by Huggo

I like when AM (Ann Marie) has to audition for parts in TV commercials. There is always an earnest desperation in her attempt to get cast that is funny. This episode reveals that MT (Marlo Thomas) got all the on screen charisma genes from her dad, while her siblings apparently got none. Her brother and sister seemed to have gotten all the musical talent. Tony, being the drummer, is of course the most talented Thomas because everyone knows drummers are the most talented people. I'm not saying that because I play drums. I'm saying that because it is the truth. The scene near the end when Ann bumped into the priest really made me laugh. A great pay off to family affair humor threaded through out the episode.
