............. Teeteringhead,
I should have refreshed my memory but my Debrett's "Correct Form" is missing from its place on the bookshelf
However, my gaff is small in comparison to that (actually 'Those') made at a well known RAF station in the south of our homeland.
At a big ceremony (middle ranked Royal on parade) several things happened, not including the gates not being opened until 20 minutes after calling time, thereby ensuring the road outside said base was gridlocked.
First, the seating cards had "Air Marshal The Lord 'X' and the next chair? - "Mrs 'X'".
HM's Lord Lieutenant was unescorted (and largely ignored by the unit's brass).
Despite being contacted by the unit but a day or so before, another 3* and his lady were missed off the seating plan.
The 'Royal' was not announced and it was left to the keynote speaker to introduce himself and acknowledge the presence of the Royal - followed by a frantic scramble for seats!
A line of squadron standards being paraded were ignored by many (in uniform) who passed them.
To cap it all, the Royal's microphone was not switched on (nor was any attempt made to do so) and his speech was nothing but a silent moving of the lips (it would be in poor taste to suggest this might not have been a bad thing)
All in all not a good show!!
The saving grace was that the gang of mates I was with - having not been invited to dine - decamped to a very nice pub nearby and had a most enjoyable get together.
AND ........... on your second tack - yes - the Headmaster is happy to be called by his first name, if I could only remember what it is
O-D
