Mumblin len learnt this one as a recitation while he was at school in the '60s. the lyrics went as follows:

The doggies had a meeting, they came from near and far,
Some came by motorcycle, and some by motor car.

And as each dog came in the hall, each signed a little book,
And hung his little tiddler upon a little hook.

One dog was not invited, that sorely raised his ire,
He ran into the meeting hall and loudly shouted FIRE!

The dogs were in confusion, without another look
Each grabbed for any tiddler from off of any hook.

And that is why when two dogs meet, on land, abroad or home,
Each sniffs the others tiddler, to see if its his own.


There wasn't a tune, as far as he remembers, but the guy he learnt it from had heard it from his grandfather, so it must go back a fair way!
