Broadcast live at 3.30pm on 14 July 1930, the play was produced from a small studio in the Baird Company headquarters at 133 Long Acre, London. The play was chosen because of its confined setting, small cast and short length, and was directed by Val Gielgud, who was at the time the BBC's senior producer of radio drama. Because of the primitive 30-line camera technology, only one figure could be shown on screen at a time and the field of vision of the cameras was extremely restricted. The Prime Minister of the day, Ramsay MacDonald, watched the play with his family on the Baird Televisor Baird had previously installed at their 10 Downing Street home. The reviewer for "The Times" newspaper commented that: "This afternoon on the roof of 133, Long Acre will prove to be a memorable one... The time for interest and curiosity is come, but the time for serious criticism of television plays, as plays, is not yet."
