The Beiderbecke Affair is a television series produced in the United Kingdom by ITV during 1985, written by the prolific Alan Plater, whose lengthy credits in British television since the 1960s included the four-part mini series Get Lost! for ITV in 1981. The Beiderbecke Affair has a similar style to Get Lost!, wherein Neville Keaton (Alun Armstrong) and Judy Threadgold (Bridget Turner) played in an ensemble cast. Although The Beiderbecke Affair was intended as a sequel to Get Lost!, Alun Armstrong proved to be unavailable and the premise was reworked. It is the first part of The Beiderbecke Trilogy, with the two sequel series being The Beiderbecke Tapes (1987) and The Beiderbecke Connection (1988).
