Hi again Bob,

The version of the dog's meeting we recorded was from Bill Boundy and we always introduced it with the Lawson story and over many years, never met the "reputable authorities" who doubted it. Collecting bawdy songs around Australia was a hobby of mine in the late sixties and I heard a similar song to yours - I think in Townsville when I was living there is 66-67. It was also to the Lincolnshire Poacher and went like this:

The baker's boy to the Chandler went, some candles for to buy
But when he got upon the spot, no one could he espy
And just as he was about to leave, thinking that all was dead
He heard the sound of a rubbity-dub right above his head

Now the baker's boy was cunning and wise and he crept up those stairs
He went into the bedroom and he caught them unawares
For there he found the butcher's boy tween the chandler's missus's thighs
And they were having a rubbity-dub right before his eyes

Now the chandler's wife got such a fright that she jumped out of bed
And she turned to the baker's boy and this is what she said
If you will just my secret keep, then bear this fact in mind
You can always come round for a ribbity-dub whenever you feel inclined

Now the baker's boy was filled with joy at the prospect of such fun
He vowed he'd leap upon the bed when the butcher's boy had done
But when he came to the shorter strokes as he shagged that chandler's wife
He vowed he'd have a rubbity-dub, every day of his life

But in the morn when he awoke, all over he did shake
His back was sore, his balls were raw, all over he did quake
And when he looked at his Long Tom he saw he'd done the trick
The consequence of his rubbity-dub was pimples on his prick

Now to the doctor he did go, some ointment for to buy
The doctor looked him up and down and heaved a mighty sigh
My boy! My boy! the doctor said, You've been a bloody fool
You'll never more have a rubbity-dub, I'm gonna cut off your tool

So listen to the baker's boy for he should surely know
An enthusiastic amateur is worse that any pro
And if you would a-wooing go and self control you lack
Whenever you have a rubbity-dub be sure to wear a mac.

I'm pretty sure I got this at the James Cook Uni in Townsville so it must have been in circulation. The fairly literary style suggests that it probably came from one of the uni songbooks that were popular then and the reference to a "mac" suggests that it's probably English. It's a great song, if you pick the right audience.
