.. who can forget when Thatcher forced them to put actors' voices in the place of Irish politicians?

Que? I didn't know that! Care to reference pls.

For info, I remember a bloke coming into the pub where I served drinks and this guy walked in with his arm in the sling declaring he was near a post box that blew up near him .. 70s thereabouts. London.

Just sayin'. I am not totally ignorant. Hence a reference would be appreciated.
