Curtain call for Last Post

Just a couple of days to Remembrance Day but after Remembrance Sunday, mentions of the Last Post (or horror of horrors, The Last Post) will subside.  It is as gauche as saying Lake Windermere and if you are paying respect to the fallen, you might as well do it properly.  In this, Wikipedia is no help, having it as "the 'Last Post'" (though thankfully has 'Reveille' without the definite article).  To be fair, I too was unaware of this linguistic disposition but having read The Telegraph Style Guide, it has stayed with me, indelibly imprinted, thus to be forever frustrated by the non-cognoscenti.
