Boycie and Marlene have been married for nearly forty years so Marlene is planning a huge party to celebrate their Ruby wedding anniversary. A marquee and caterers have been booked, the flowers are being organised and a band has been booked to play their song – "What's New Pussycat?" Meanwhile, the guest list has grown to an enormous length and Marlene has contacted their old Peckham solicitor. However, he brings bad news – the registrar who married them was unlicensed, so they have never been married.
