Emily starts a petition against the disco. The Cheethams decide they want to buy No.9. Ken annoys Alf by putting a disco protest poster in his shop window. Annie phones Douglas Cresswell at Newton & Ridley to talk about the disco. Mr. Cheetham offers Chalkie £10,500 for the house, including fittings. Chalkie agrees. Annie is furious to discover the brewery is backing the disco; it's going to sell Newton & Ridley beer. She realises her trade is going to suffer. Phyllis meets the Cheethams. She puts them off buying No.9 by telling them about the planned disco. Mike offers Hilda a job as cloakroom attendant so she withdraws her name from the petition against the disco. Mike tells Ken he's going to lose this battle.
