Quite correct Bernard, I have first hand experience:
Re: What's your claim to fame.......
Back in the summer of 1968 while waiting to go to college, I was working for a company in Cricklewood that supplied juke boxes and fruit machines to clubs and pubs in the London area. One evening, the boss asked for 2 of us to work late on a huge juke box installation in the Windsor area, so we set off in the van along the M4 and as we approached Windsor I looked at the job sheet to find the address - Windsor Castle!
It turned out that HM put on a huge party for her offspring every year based in the games room at the castle, a huge room with a wooden polo pony on springs surrounded by a net as the centre piece. After dragging all the kit in, my job was to connect everything up, so there I was trying to hide the speaker cables behind all the exotic plants when a pair of playful dogs leapt up and grabbed the bottom of my t-shirt. Somewhat surprised, I let out a 'get down you b**tards' and sent one of the dogs flying with a smart back hander. At this point I was suddenly aware of a casually dressed female who was taking three Corgis for a tour of the grounds, and my immediate thought was that she looked very familiar.... Yes, you have guessed it, HM herself, grinning from ear to ear at my antics.
Bashing a royal mutt, swearing at another, I was expecting to get arrested on the spot, but as far as I could see there was no visible security and HM came over and chatted for several minutes before continuing her walk. Later as we were testing the system, Andrew and Edward appeared but were most concerned that they had no money and would be unable to play their favourite top 20 tunes. Needless to say the machine was set to free play and I showed them how to pre-select a number of records. From memory the princes were 6 and 10 at the time, and the Corgi soon recovered and made friends.
