I was going to say there was no delay visible here,but decided that any delay would only be a few seconds(Big Ben clock said the same time as my clocks)and thus,invisible leaving me looking like a pratt. :)
I think that is the problem as light does travel faster than sound. They would have to delay the pictures in the Mall to synch in with the sound travelling from the stage. To my mind the difficult part would have been synchronising in Madness playing on the roof to the orchestra playing on the bandstand. Must be quite clever really and certainly light years ahead of my days standing in front of Marshall Amps trying not to get feedback.
If you started out at the same time as I did then Vox were the bees knees of Guitar Amps especially their AC series so making do is really an understatement. Marshall were the new boy on the block at the time and certainly didn't have the kudos they have now or the kudos of Vox at the time.
Selmer were a London Company that re-badged other peoples' stuff and sold it under their own name. Likelihood was that the Goliath was German and probably Hofner who of course made the cello bass which Paul McCartney played in his Beatles days but I stand to be corrected. Subsequently bought out by CMI (Chicago Music Industries) who are the parent company of Gibson & Epiphone hence Paul's current bass showing as a Gibson. Vox made good stuff and their speakers were I think from Celestion who later became a household name for quality Hi-Fi speakers. Those were the days and of course no connection with my current need for a hearing aid.
