Lyrics:

One boy
Boy for sale
He's going cheap
Only seven guineas
That -- or thereabouts

Small boy...
Rather pale...
From lack of sleep
Feed him gruel dinners
Stop him getting stout

If I should say he wasn't very greedy...
I could not, I'd be telling you a tale
One boy
Boy for sale
Come take a peep
Have you ever seen as
Nice
A boy
For sale
