It is part of the fabric of British life and many people still have a fond relationship with their 'postie', who walks down their path bringing their letters and parcels to their door.

The 1970s ITV series was a critical and popular success and also found a fond audience in the United States, where it aired on PBS.

Adolescence is now among the programmes with the highest seven-day ratings so far this year, behind the BBC's The Traitors, Call The Midwife and the Gavin & Stacey: A Fond Farewell documentary.

Appearing as part of the new BBC iPlayer documentary, Gavin & Stacey: A Fond Farewell, the short clip shows Uncle Bryn and Jason in a home video.

Gavin and Stacey: A Fond Farewell is available to watch on BBC iPlayer.
