Very good Smokey, do you recall

"There was a young farter from Sparta,
A really magnificent farter,
On the strength of one bean
He'd fart "God Save the Queen",
And Beethovens Seventh Sonata.

He could whistle, could warble and hum,
By constricting the hole in his bum,
And make animal sounds,
Or fire artillery rounds,
With the force of a field cannon gun."
