When Susie Long appears, together with her 20 year old son, Pink and Pound are thrown into confusion that one of them could be his father.

In this film, specially taken for the BBC, viewers are given an idea of the growth of the television installation at Alexandra Palace and an insight into production routine. There will be many shots behind the scenes. One sequence, for instance, will show Adele Dixon as she appears to viewers in the Variety at 3.30 this afternoon, and will then reveal the technical staff and equipment in the studio that made this transmission possible.

Calling the Tune offers a fascinating look at the fledgeling gramophone industry as it tries to solve the problems of reliable recording and production methods. 'I predict that the gramophone will be the democratic entertainment of the future' states unscrupulous record label boss Mr Gordon (Sam Livesey), who finally gets his comeuppance after one dirty trick too far against his rivals. If the film's love story is perfunctory, the real interest comes with watching performers of the day, from Henry Wood and his orchestra to George Robey and Charles 'the laughing policeman' Penrose laying down their recordings direct to record. And something very like a prototype laser disc makes a crucial appearance too.
