Many of the jokes were topical, featuring references to well-known personalities of the day: not only showbusiness celebrities (everyone from comedian Ken Dodd to actor Roger Moore), but also BBC presenters (including Michael Aspel, Frank Bough, Nicholas Parsons and Terry Wogan), politicians (especially the Prime Minister, Harold Wilson, and the Leader of the Opposition, Mrs Thatcher), sportsmen (such as England international footballer Martin Peters), and prominent personalities of the day (the inevitable references to clean-up-TV campaigner Mary Whitehouse, and the anti-immigration MP, Enoch Powell).
