Graham Kerr, an Australian cook with a cheesy grin, used to cook something and at the end he would invite a member of the audience to join him at the table to eat it.
Crown Court was a half hour drama about -guess what - people in court, and at the end of the third episode it used to have 'The Verdict' .
Rooms was about people living in bedsitter land, coming and going, and Peyton Place was an American drama.
