THE GREY MAN
(Words by John o' the North
Music by Ruth Mervyn)

On a summer day, quiet and still
The grey man came across the hill,
Tall was he and long his stride
and he cast no shadow at his side.
Tall was he and long his stride
and he cast no shadow at his side.

Tall and forbidding stooped and grey
and a chill went with him on his way.
Down the path I watched him go
where it falls away to the rocks below.
Down the path I watched him go
where it falls away to the rocks below.

Over the boulders and through the scree
Down he went, Down to the sea,
And I have heard that it bodeth ill
to see the grey man cross the hill,
But well or ill or sun or rain,
I never wish to see him again.

Words by John o' the North

I think this song is about the grey man described in this article. I came across it in a harp book in the library when I was in Dublin 18 years ago.
