As a very junior officer I was let loose with QCS to do a few stints at 'Changing the Guard at Buckingham Palace'.....I remember with great fondness the weeks of painful one-on-one sessions with the squadron WO on the Uxbridge parade square before I was let loose in front of Joe Public.
By the end of it all I could muster a reasonable bit of sword action and generate copious amounts of 'Seg' sparks when doing the trademark 'sliding' halt! Never quite managed to get any 'revurb' in my saluting though...left that all to the troops who could get a good 30 seconds of 'twanging' when required.............
