This episode was selected by series lead Jack Warner as his favourite - presumably from those actually still available to repeat at the time - on Sunday 3rd August 1969's edition of "Star Choice" on BBC1.
Johnny Wills' face isn't seen when he stands up during Andy's briefing, and the scene quickly cuts away. Nicholas Donnelly only appeared in the pre-filmed location sequences, not the studio session.
Having now reached his early 70s himself by the time of production, lead actor Jack Warner went out of his way to assist Age Action obtain film copies of this hard-hitting instalment, for special screenings at OAP retirement groups to help spread the word about the type of scammers the episode centres around. It's possible that this laudable public service reason is why the edition was retained by the BBC Archives.
