DIARY: You must remember

Unfortunately, no-one managed to win last week's quiz. The correct answers were: 1. Chicago Town; 2. Listerine; 3. Pedigree. The theme was dentists. This week, we want you to identify the ads and the theme. Fax your answers to (020) 8267 4914/4915 or e-mail campaign@haynet.com by close of play on Friday 4 April. The winner will receive a bottle of Champagne.
