A Rule of the A.J.C

Come all ye bold trainers attend to my song,
It's a rule of the A. J. C.
You mustn't train ponies, for that's very wrong
By the rules of the A. J. C.
You have to wear winkers when crossing the street,
For fear that a pony you'd happen to meet
If you hear one about, you must beat a retreat
That's a rule of the A. J. C.

And all ye bold owners will find without fail
By the rules of the A. J. C.,
The jockey boys' fees you must pay at the scale
It's a rule of the A. J. C.
When your horse wins a fiver, you'll laugh, I'll be bound,
But you won't laugh so much by the time that you've found
That the fee to the boy is exactly ten pound!
That's a rule of the A. J. C.
