Alf Observes the 2-minute Silence (1974) 

@HeathH737 Possibly Television was still black and white then but not the original medium used to film the series i.e. colour film?

FrozenDoberman, where did you get the information regarding the Australian transmission date? And good clip by the way, although I prefer Archie Bunker over Alf Garnett myself.

Wait, wasn't colour TV in Australia started in 1975?
