There's a great song by Scottish songwriter, Ian Walker, which uses Robert Burns' Selkirk Grace as the chorus: not only does it mention children going hungry, but also the vast waste of food in other areas.

SOME HAE MEAT      (Ian Walker/Robert Burns)

From my armchair window on this world
Before my eyes appearing
Foods for breakfasts, dinners, teas
For in between meals feeding

Chorus

Some hae meat and cannae eat
Some would eat that want it
But we hae meat and we can eat
Sae let the Lord be thankit

From my armchair window on this world
I see butter mountains rising
And fish thrown back into the sea
And leaders compromising

And then I see one bowl of rice
A child’s eyes staring at me
With feeble bones life never owned
Reaching out to touch me

Just down the road a million miles
Our children they are crying
Too weak to eat, they’ve got no meat
They spend their living dying

But the ill divisions of this world
Exist because we let them
The choice is ours, ‘tween need and greed
To help or just forget them.

And here he is singing it with Ian Bruce:
Some hae meat
