Quiet biker Malcolm, who lived with his domineering mother (played by Patsy Byrne), was accompanied on his birdwatching trips by loud scouser Brenda, who was forced to ride in the sidecar of his Norton motorbike and had a habit of rubbing his mother up the wrong way. Other key characters in the series were Brenda's sister Pamela (Liza Tarbuck), her husband David (John Bowler – Series 2 onwards) and Brenda and Pam's mother Joyce (played by Noreen Kershaw) in the last few series. The series followed Malcolm and Brenda's on/off relationship, during which Malcolm married another woman called Lucinda (played by Elizabeth Morton). However, Brenda and Malcolm finally married each other in the final episode, "Knotting", which was broadcast on 4 April 1993.
