I have been involved with the project management for the Cenotaph ceremony for the last twenty years. In 1995 the company that I worked for bid and won the contract to provide the sound systems. The actual requirement, just like the ceremony, has not changed since then.
Last year the contract was awarded to my company and we now provide all the microphones and loudspeakers that cover from Parliament Square, up Whitehall to the top near Trafalgar Square. The microphones are used to provide the sound for the BBC TV & radio and for public security.
This year I also looked after the sound system in the room where the heads of the military and faiths meet with the politicians and ambassadors prior to the ceremony. This is when I met Rev Steven Wild -- our Methodist President. He was circulating the room talking to everyone; it was a privilege to see him in action and join him for a "selfie" which he posted on Facebook. Our son, Andrew, operates the live sound system and he is photographed here with Rev Steven Wild and me.
