I'd answered you at folkinfo Mr H but I don't suppose a copy/paste here will do any harm.

Here you go, Mr H, Singing Together Spring 1971. Credited there as a Welsh Folk Tune with Words By Barbra Kluge.

There once was a shepherd who lived on his own.
Away on the hills in a hut built of stone.
He guarded his sheep and they kept to the trail,
So the shepherd whistled gaily and the dog wagged his tail.

In springtime he watched how the lambs in thier play
All kicked up their hooves and then darted away.
The dog fetched them back if they strayed to the dale,
So the shepherd whistled gaily and the dog wagged his tail.

In winter he sheltered away from the cold
With his dog by the fire. while the flock in the fold
Lay safe from the blustering, buffeting gale,
So the shepherd whistled gaily and the dog wagged his tail.

I loved that song as a kid but I'm not so sure of the words now...

Jon
