What began as a "what shall we do because the person who was going to take assembly has failed to show up?" has turned into a regular Friday fixture.
As a headmaster who has enthusiastically led whole-school singing for a decade, I support without reservation Marc Jaffrey's ambition to establish a national singing strategy.
Like him, my recollection of my own school assemblies was a daily ration of traditional hymns. Now, in a more cosmopolitan 21st century, we sing the traditional, modern and the secular: "Cockles and mussels", "Little brown jug". I could go on.
But is it of any value? Of course - you should hear the volume from what many might consider to be the reluctant mouths of the average tuneless teenager.
My only regret is that next year I will not be there to witness another generation sing their hearts out, as I will have left the school. However, I understand this quirky practice is likely to continue here in middle England, where quite literally schoolchildren thank God it's Friday.
