I can't, for the life of me, recall the tune - but there must be one - and lyrics too, that somehow also evade remembrance.
Definitely the sort of thing for the Proms, certainly it would be sung in it's entirety at the close of all Civil-Servant Christmas parties to send all home with heart up-lifted and spirits a-soaring.

If they were to identify shortcomings in book-keeping, and threaten to return, things could improve, but if the intention is to issue demands for payment (calculated through statistical niceties rather than intense investigation) these demands may very well be the final straw to many a small business.
