The private trumpet-eer

It was a natural gift
Given to Jonny Swift
He could play almost any tune
But would only trump in his own room
We’d hear wonderful sounds
Coming from under the door
Though when we peeped in
Jonny would trump no more
Come and trump in my room
His sister Kath used to say
That made Jonny mad
And he’d trump so loud
You could hear him
On the moon.
