Many years ago I got tickets for the Final Rehearsal for the Queen's Birthday Parade at Horseguards. Tickets said "uniform or Lounge Suit" so I wore my best blue, as one does. Leaving aside the need (my wife is not known for timekeeping, other than "bad") to run down Whitehall, and remembering to " march" past the Cenotaph so I could salute, and arrived in the tiered searting just in time, to realise that of the several thousand specrtators few of us were in uniform, although may of those present were clearly serving. Did a lot of saluting that day too!
