This was filmed outside Derrick Days home on Hyde Road,Hoxton,East London probably in 1977. Around the 8 second mark, there is a clip of SEARCHLIGHT/IRA/reds attacking us at the Moss Side, Manchester bye-election of 1978. At the start there is a clip from the reds attacking the Lewisham NF march in August 1977.
All the vid is about 'reds' attacking the National Front in the 1970s.
The 'reds' just happened to have a TV camera pointing at Derricks home, which was on the bottom floor and where he climbs out of. I wonder what provocation they had done prior to the filming, just as they have done to Emma West ?
I wonder how DD would have gone on riding the London trams ?
