When you have the tune, you may prefer to sing this! Don't know the origin - possibly Australian

Unless my watch is fast the morning is now past
And to speak of noon is too late in the day.
I'm feeling very bad and my heart is very sad -
I'm thinking of my old dog Tray.
Old dog Tray was ever faithful
But disaster came upon him one fine day
For those governmental hacks would insist upon the tax
Which was fatal to my old dog Tray.

He was very good with cats and a mortal foe to rats
More like a brother than I care to say;
But five shillings every year for a dog is very dear –
It was too much for my old dog Tray.
Old dog Tray he got a plateful
Of meat and potato one fine day;
But among that savoury mass I hid a dose of Prussic Ac -i- id
Which was fatal to my old dog Tray.

They bore him from my sight and it did upset me quite
And very soon I wasted near away;
From every meal I turned and all my food I spurned
From thinking of my old dog Tray.
But old dog Tray I met again though
When I started to eat again one day
For in Tesco's mutton pies I've come to recognise
The flavour of my old dog Tray.
