The Beiderbecke Trilogy refers to three television serials written by Alan Plater and made by Yorkshire Television for the ITV network in the United Kingdom between 1984 and 1988. Each serial centres around schoolteachers Trevor Chaplin and Jill Swinburne who work at a rundown comprehensive school in Leeds. Woodwork teacher Trevor enjoys football and jazz music while English teacher Jill is a political activist concerned with saving the environment.
In each of the three serials – The Beiderbecke Affair, The Beiderbecke Tapes and The Beiderbecke Connection – Jill and Trevor inadvertently become embroiled in a series of unlikely adventures involving such things as political corruption, nuclear waste dumping and serious fraud. In each serial, the plot rambles, moving from one seemingly unrelated event to another, all of which are eventually shown to be interconnected. However, it is the clever interplay between the characters that is the core of each these stories.
Each episode unfolds to a soundtrack of jazz music in the style of Bix Beiderbecke performed by Frank Ricotti with Kenny Baker as featured cornet soloist. Extensive use is made of leitmotifs for the various characters. Ricotti won a BAFTA award for his work on The Beiderbecke Connection.
