I my opinion...(not that most care) The very best song about The Corncrake..or Crake is Jez Lowe's song - The Crake in the Morning: Fabulous tune and a wonderfully evocative story and memory...

Crake in the Morning - Jez Lowe.

The crack of the rattle woke me up with the lark this morning
Sudden as a thunderclap from hell,
It could’ve been a dream I had,
It could’ve been I’m going mad,
But perhaps you have heard as well.
An echo, a spectre over ages gone by it flew
Up and down empty Sunday streets
The rasping of the morning crake
The whole world and his wife to wake,
From a time with easier sheets.
Still the sound of the rattling crake in the morning.

I held on my breath to hear the next that I knew would come
The throttle of a voice with these words,
A meeting will be held for all,
This morning in the Miners Hall,
If you’ve a tongue in your head you’ll be heard.
And the rattle kept turning getting louder and louder
And I clapped me hands hard on my ears,
It clattered back a memory,
Of Sunday morning used to be,
Till it took to the sky and disappeared.
Still the sound of the rattling crake in the morning.

I slid to my window and peeped out on the street below
Slapped by the sight that I saw,
Men dressed in their Sunday best,
To start their hard earned day of rest,
By answering the Crake’s morning call.
But even as I was wishing them on their way
I saw them fade at each step they would take
As fade away they did I know
Now many, many moons ago,
Like the song of the crack of the crake.
Still the sound of the rattling crake in the morning.
Still the sound of the rattling crake in the morning.
