A version of the play was performed in Perth in 1963, the first television drama made in that city. It was broadcast in Melbourne on 9 September 1963.[6]
The producer was Bill Eldridge who described the play as "something between the kitchen sink and the twilight zone, one of Priestley's 'time' plays concerned with the reaction of ordinary people to an extraordinary situation."[7]
