The Ballad of the Black Robin

​
They called me ‘Old Blue’
It was such a to do
There were five of us left in the world
Even though an old maid
The eggs that I laid
Were beautifully mottled and pearled
It was in 1980
When life became weighty
With only the five of us left
There were four males and me
And our destiny
Was extinction. We felt quite bereft
They trapped us in boxes
The strange paradox is
They were trying to let us be free
We were shipped at some pace
To a suitable place
But survival was no guarantee
I laid eggs in my nest
And they all thought it best
To move them to nests of tomtits
Where they hatched and were raised
(Let their efforts be praised)
And we all were quite thrilled to bits
Now thank to Don Merton
Our future’s more certain
Survival looks well on the cards
We’re protected and cared for
And folks are prepared more
For times when things might become hard
Nearly three hundred strong
We can now sing our song
As a chorus of hope and success
And pray others just might
Take up Earth’s awful plight
And fight to get out of this mess
