Name That Tune

[chappie]

Any ABers know the name of this song and/or artist please? It goes something like this:

Yes I know you're hungry and we've got food to spare,
we're throwing our surplus food away but don't think we don't care.
We can't afford to send the stuff to the places where you are,
but you can thank your lucky stars, there's someone, somewhere, much worse off than you are.

It is an old song. I have been trying for ages to find it, but no-one seems to remember it.

Many thanks.
