It's the soles of the people he keeps in view,
For he is the doctor of the boot and shoe;
He serves the living and not the dead,
With the best of leather wax and thread;
He can sew on a sole and make it fast,
And do a good job and make it last;
He doesn't use poultice, plaster or pill,
He cures all sick shoes no matter how ill.
